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 fitted 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.

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-
gured 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 dee-
nergizes, 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.
2.5.2 Load monitoring (undercurrent monitoring)
Thyro-S ... H RL1 is suitable for monitoring loads resulting from one or
several resistances in parallel or parallel series connection.
Thyro-S detects an increase in the load resistance. The load monito-
ring operates as undercurrent monitoring on absolute values and is
suitable for use in the nominal operating mode 1:1, and with limita-
tions in the operating modes 1:2. 1:3 and 1:5.
The load monitoring is supplied with the default configuration OFF =
left stop R205 (=0)
For all other configurations:
If the load current falls below the level set the error indication relay will
respond with a delay (4-10 sec depending on operating mode). The
result is indicated via an optionally connected bus system.
This can be set in accordance with the following table.
2.5.3 Load monitoring (overcurrent monitoring)
Along with undercurrent monitoring 2.5.2 the device also has over-
current monitoring. This can only be configured using Thyro-Tool
Family.
