The Monitoring device KEU 371 can be used as an upgrade of the automatic control unit KEA 071 - 073 or as a single appliance. A maximum of 32 fault signals can be monitored. Of these, 16 are registered over contacts connected to the positive charge of the battery. For these messages, openers as well as shutters can optionally be used. A further 16 Alarms can be released by contacts or derived by analogue signals. The Alarms are labelled by text insert strips, so that it is remains possible to easily rename or expand. The appliance is only available for a distribution voltage of 24 volt. In case the appliance is used as a supplement to a KEA 071- 073 it can be connected to the KEA control unit by an optical fibre conductor (OPC). Further connections are not needed to that purpose. All necessary parameters Parameter can be typed in with a PC (Notebook). The corresponding program belongs to the delivery, the required OPCadapter and the OPC are the same as the ones required for the automatic control unit KEA.

Apart from the eight digital inlets, eight analogue channels are available. Every channel can alternatively be equipped with a sub printed circuit board for registration of the following transmitters: ∗ ∗ ∗ ∗ ∗

PT 100, PT 1000, Thermo couple NiCrNi, Current loop 0 (4) - 20 mA, Two contact transmitters.

In case an analogue value is being monitored, every limit value releases a pre – alarm and a main alarm. Limit values with the correct sign indicator are entered in, so for example: for reverse power, a negative value can be entered. Alarm can be given optionally for over or undershooting the limit value. Every analogue channel can also be mapped out to take two digital contacts so that a further 16 alarms can be derived out of the eight analogue channels.

DESCRIPTION OF THE HARDWARE The KEU 371 is comprised of two hardware parts: one KMS-element which registers and assesses the alarms, as well as an indicator panel which is fitted at the front of the control box. Both appliances are connected with an optical fibre conductor. This makes wiring easy because the panel only needs 24 volts. The monitoring is then completely guaranteed should the panel break down or if the PFO disturbed. The control panel accepts the following signals: * *

Life signal signifying that the system is OK. Instruction: order to switch the generator in case of disturbance, ∗ Stop instruction of the shutting alarms, ∗ Sound alarm switch on. The KMS-Element provides the following instructions: ∗ Drive of the stop magnet, ∗ Drive of the operative magnet, * Instruction to turn off the generator in case of disturbance, ∗ Common alarm danger (Warning), ∗ Common alarm disturbance (Stop), ∗ Message ‘Motor running. The following inlet for contacts (connected against plus potential) are accessible: ∗ Inlet ‘Motor is running’ ( generator D+), ∗ Stop (emergency stop) ∗ 16 Inlets for alarm messages . Furthermore, there is an inlet for the connection of a pick up or of a tachometer generator for measuring the number of revolutions. The following functions or encoding can be classified with a PC (Notebook): ∗ Encoding of fault signals: warning / shutting, delayed / not delayed Transmitter N.C. circuit / N.O. circuit, Generator switching off / not switching off ∗ delay ‘Controls on’, ∗ Operating time sound alarm, ∗ Instruction duration stop magnet, ∗ Limit value in case of analogue processing, ∗ Allocation of incoming messages to the LEDs, ∗ Delay times for every fault message for debouncing, ∗ Classifying pick up inlet / tachometer generator.

Furthermore, the parameters of the data traffic can be classified with the PFO. These changes have to be made after consultation with the manufacturer. The eight analogue channels can be used to register analogue or digital signals. Use sub - circuit boards in order to do this. Connect the transmitters PT 100 and PT 1000 to the N + N technique. The digital signals need connected plus potentials. The sub - circuit boards PT 100 and PT 1000 register the 60 - 120°C ranges with a resolution of one degree. Other ranges (0 - 60°C, 80 140°C)can be delivered upon request. The thermo couples (NiCr-Ni) are measured within the 250 - 750°C ranges. The resolution, here, is of 2 °C. In current loops a conversion for the range 0 - 20 mA or 4 - 20 mA can be selected. The resolution for the range 0 - 20 mA is of 1/250 of the maximal value. The KEU 371 can be used as an autarchic appliance as a fault extension of an automatic control unit KEA 071 - 073. When it is operated as a fault extension, it can be coupled over an PFO with the automatic. In which case, all the signals are transmitted over the interface. Then, the functions of the touch button stop, lamp test and alarm off in fact connected in parallel. In addition to the touch button functions, the signals ∗ ∗ ∗ ∗ ∗

Sound on, Stop, Generator should switch off, Common alarm danger, Common alarm disturbance

are transmitted to the KEA. The KEA assigns the following signals to the panel: ∗ Monitoring switch in position ‘OFF’, ∗ Controls on ∗ Motor is running. The panel is equipped with an interface for to connect an automation control system. When it is in use, all the fault signals of the KEUs and, in case they are available, the correctly converted analogue values are also transmitted to the automation control system. When a KEA is connected over PFO, the fault signals are additionally given from the KEA as

well as, if any, supply and generator voltage and frequency, battery voltage, Generator power and

07/97 speed. These analogue values now have to be converted in the automation control system.

FAULT MONITORING Fault signals are basically differentiated into two groups: ∗ The release of the operational fault signals is delayed (e.g. Low Oil Warning) to appear only after the start of the unit, recognisable by the

LED-signal CONTROLS ON, ∗ Fault signals independent from operations (e.g. Low-volt battery) are constantly activated (apart from the optional switch position OFF, when coupled to a KEA over PFO)

If required, the signals can be classified as follows:

the same time the sound Signal (for the duration set) is released.

∗ for signals’ contacts in N.C. circuit and N.O. circuit, ∗ control only whist unit is running or also with standstill unit, ∗ only warning signals or with simultaneous stopping unit, ∗ in addition to warning signals: − without generator shut off, − with generator shut off.

The sound signal is turned off by impulse of the touch button ALARM OFF (or automatically after a set duration) whereby the flash light turns into a continuous light. Many warning signals happening one after the other can, by this device, renew the release - with single display in flash light – of the sound signal.

Contact inputs release single signals by shutting (N.O. Circuit) or by opening (N.C. circuit) the contact signals against minus potential, or with analogue signals by over or undershooting (according to the single classifying) of the set limit values. After a classified delay (0 - 25 sec.) the signal is saved and shown by the LED in flashing light. At FUNCTION

Usually, the disturbance signals of the works are entered in accordance with the requirements stated in the order. Yet it is easily possible to undertake alterations or supplementary classifying with a PC or notebook.

DIL-SWITCH

On the back page of the panel there is a block with micro coding switches. they have the following meaning: (from left to right): 1. 2. 3. 4.

The display is cancelled after removal of the disturbance by re –pressing the touch button ALARM OFF.

Classifying access to KMS free Data exchange to PFO free Connection to a KEA as extension Data exchange to KMS free (the switch must always be closed) Classifying of the panel free Classifying of the KEA free Reserve Life signal on LED CONTROLS ON

The classifying of the KMS-element is described in the user handbook S176000101.

If the Appliance is to serve as fault extension of a KEA then the third switch should turned off. Furthermore the KEA needs Software to date at Version 15 or higher and the data exchange to the KEU must be released by classifying the KEA.

The fourth switch must always be shut! It only serves testing purposes of the Appliance. Since the front of panel is dark when the machine is not running and when there is no actual alarm, it is possible, by shutting the eighth switch, to enter a life signal onto the LED CONTROLS ON. It flashes in that case every 5 seconds for about 100 msec.

CONTROLS ON With this green LED, (after the unit started) the release of the operation dependant delayed disturbance detecting circuit is signalled. During the self reliant (without KEA 071) running of the KEU, the start is registered either through the inlet GENERATOR D+ or through the Revolution transmitter signal (Pick-Up, tachometer generator). After the start of the machine the LED starts to flash until, at the issue of a delay, it turns to steady burning light. The display expires after the beginning of the shutting down procedure.

When the KEU is coupled to a KEA, the LED is triggered after expiry of the delay CONTROLS ON in the KEA. No flashing is intended for this case because the LED in the KEA behaves accordingly. In intact appliances, these flash LED in case of machine stand still for around. 100 msec. as life signal. In order to release this function, the switch 8 of the DIL-switch bloc must be turned off.

the data exchange is flowing again, they stop flashing five seconds later, or they display the signals status.

When the data exchange between the panel and the KMS or, in case this is arranged, between the panel and the KEA is disturbed, then both LED start to flash alternatively after 10 seconds. When

The LEDs flash likewise when classifying of the KMS element is selected because in this case no fault monitoring is taking place.

OPERATION- AND STOP MAGNET When the motor has started, the ‘running’ - signal operation magnet is excited straight after detec-

tion until either the ‘running’- signal is discontinued or a stop command ensues.

OUTLET SWITCHING OFF THE GENERATOR The Fault signals can be classified in such a way that, in case of disturbance the generator is switched off, yet the motors still runs. This is for example sensible in case of a GENERATOR

OVERLOAD – signal because the generator cools down thanks to the machine which continues to turn.

OUTLET COMMON ALARM DANGER, OUTLET COMMON ALARM DISTURBANCE When a warning fault signal arises, the outlet COMMON ALARM DANGER is activated, when a

turn off signal appears, the Common Alarm Disturbance is activated.

RUNNING MESSAGE, GENERATOR CLAMP D+ The indication that the motor started, occurs either through the inlet, generator clamp D+ or through a pick-up or a Tachometer transmitter. The outlet is activated as soon as one of these signals is detected.

When the KEU is coupled to a KEA, the registration of the revolutions occurs through the KEA. This outlet is also triggered here.

CONNECTING THE KEU 371 TO A KEA 071- 073 In case the KEU 371 is used as a fault extension of a KEA 071 - 073, then both appliances can be connected through an PFO. Further wiring connections are not necessary. Nevertheless, the following supplementary security measures are recommended: 1. Set the Life signal from the Panel on fault signal 14 of the KEA, 2. Use the Signal TURN OFF GENERATOR directly in addition to the Generator, 3. Lay the outlet COMMON LARM DISTURBANCE directly onto the KEA or connect to an emergency stop chain. The function of the touch button LAMPS TEST and ALARM OFF are installed parallel to one anWhen the selection switch of the KEA is in OFF position, the fault controls of the KEU are turned off, as is the case in the automatic mode. The signals RUNNING and CONTROLS ON are transmitted to the KEU and evaluated there.

other, i.e. it does not matter if the touch button of the KEA or the one of the KUE is pressed. The function works on both Appliances. Pressing the touch button STOP of the KEU or setting the stop inlet of the KMS locks the automatic operation of the KEA. The Signals ∗ common alarm danger, ∗ common alarm disturbance, ∗ sound on, are transmitted to the KEA and connected to its functions, so that for example the sound is turned on when either a signal appears on the KEU or the KEA.

When the inlet ALL SIGNALS WARNING (sprinkler on) is set, then all the signals in the KEU are also immediately set on warning.

A coupling of the KEA and KEU is only possible as from Software version 15 of the automatic. The coupling must still be enabled by classifying (Menu 2, F2). Furthermore the DIL-switch 3 of the panel must be turned off. In case the data ex-

07/97 change between KEA and KEU is interrupted for more than 10 secs, then the automatic turns off the commands that might have been given until the data exchange has gone back to normal.

CONNECTING THE KEU 371 TO AN AUTOMATION CONTROL SYSTEM The KEU 371 can transmit all the data registered to an AUTOMATION CONTROL SYSTEM. In case that no KUHSE AUTOMATION CONTROL

SYSTEM is used, a protocol converter is necessary. Refer to operating instructions S176000101.
