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.

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 config-
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 flow 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 flash intermit-
tently and Bit 14 appears in the status word.
The relay function can be configured 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..
