Controlled Value; Controller Response; Led Indications - AEG THYRO-A Operating Instructions Manual

2.3.1 Controlled value

The controlled value effective on the load is proportionate to the total set point,
depending on the control type:
Control type Control value (proportionate to the total set point)
U Voltage output, U
U 2 Voltage output, U
I Current output, I
I Current output, I
2
P Power output (only with H RLP type)
2.3.2 Limitations
Independent of the voltage output control, limiting current values can additionally be
set (chapt. 3.2.3).

2.3.3 Controller response

If the load resistance changes, e.g. due to temperature effect, ageing or load break,
the values effective on the load change as follows:

2.4 Indications

2.4.1 LED indications

The LEDs on the front signal the following states:
• ON green
• PULSE INHIBIT red
• LOAD FAULT red
Blinking indications are described in chapter 3.3.
Activation of the integrated semiconductor fuse can be signalled using the K1 fault
indicating relay (undercurrent detection).
