Operating instructions

16 17
signal is interrupted up to 1.25 ms before the crossover of the full wave.
With a pulse trigger the pulse duration must be min. 1 ms.
2.2 INDICATIONS
The LEDs on the front signal the following states:
• ON GREEN operating indication, power supply controller device
Blinking indications are described in table 2.
2.3 MONITORING
2.3.1 MONITORING OF THE MAINS VOLTAGE
The limiting values of the voltage are -57% for undervoltage monitoring
and +10% for overvoltage monitoring. This produces the following
absolute limiting values:
Type Undervoltage Overvoltage
230V 99V 253V
400V 172V 440V
500V 215V 550V
NOTE
The devices may only be operated up to the undervoltage limit if he
electronics are supplied by an ext. 24V voltage. If the undervoltage
limit is undercut the pulse lock is activated and realy K1 is released
(default).

2.3.2 EQUIPMENT TEMPERATURE MONITORING
The control board is equipped with a temperature monitor.
If a fault occurs, the red LED blinks.
2.3.3 VENTILATOR MONITORING
The separately ventilated power controllers (F) are fi tted with thermal
monitoring. The temperature of the heat sink is measured. In case of
a temperature overrange a fault indication (red LED) ensues.
2.4 ADDITIONAL INDICATIONS USING TYPE S...H RL1
The LEDs on the front indicate the following situations:
• Diagnosis GREEN additonal error diagnosis
• LOAD FAULT RED error present
Flashing LED indications are described in table 2. Whether the semi-
conductor fuse is responding can be indicated by the error indication
relay K1 (undercurrent detection).
2.4.1 ERROR INDICATION RELAY K1
The K1 relay has a changer and deenergizes if an error is detected in
the system (chapter 3.2). The table shows the pin connections on the
terminal strip concerned.

Error indication relay K1 X3.1 X3.2 X3.3
2.5 ADDITIONAL INDICATIONS USING TYPE S...H RL1
Thyro-S ... H RL1 indicates errors occurring in the controller or load
circuit.
Indications are given via LED (LOAD FAULT) and via the K1 relay.
The device continues to run during errors as standard (can be confi g-
ured using the Thyro-Tool Family).
2.5.1 THYRISTOR SHORT-CIRCUIT MONITORING
The devices of the Thyro-S...H RL1 series have built in thyristor short-
circuit monitoring. If no set point signal is available at the device, the
thyristor short-circuit monitoring checks the current fl ow to the load.
If a current >10% of the controller current is measured, the indication
„thyristor short-circuit“ is given. In the case of an error the relay
deenergizes, the Test-LED as well as the Load Fault LED fl ash intermit-
tently and Bit 14 appears in the status word.
The relay function can be confi gured with the Thyro-Tool Family soft-
ware.
The indication is only given if the error has been detected 3x and the
break time is >2 mains periods..
