3.10Signalling, Displays and Remote Signals

The following signals are indicated via LEDs on the front panel:

Display	Colour	Operating status
Operation	green	INV operation
UO OK	green	INV output voltage present
UI<	red	Input voltage < 85% of rated voltage,
		INV has switched off
UI>	red	Input voltage > 128% of rated voltage,
		INV has switched off
Fault	red	INV output voltage below 90% of rated
		voltage
ϑ>	red	Overtemperature on heat sink or
		overload
Collective	red	Delayed collective fault signal,
fault		delay time 20 s,
		signalling relay is triggered at the same time.
		The following disturbing influences are
		registered:
		INV fault
		UI<
		UI>
		ϑ>
		Overload
		INV output miniature circuit-breaker

The unit is equipped with a liquid-crystal display. When the unit is switched off, the LCD shows "OFF", when the unit is switched on it shows the INV output voltage and output current. While the INV starts up and output contactor K7 is still switched off, "READY" is signalled.

In the event of a fault, the 1st display row shows "FAULT" and the 2nd display row shows the type of fault.

The INV voltage and current values are displayed with three decimals before and one decimal after the decimal point. The display accuracy corresponds to class 1 with respect to the rated output value of the unit.

Remote signalling is carried out by means of potential-free contacts via a Combicon connector on the front of the unit.

Assignment of the signal terminals:

INV fault:

In the event of a signal, X10.2 – X10.3 or X3.2 – X3.3 close. No fault: X10.2 – X10.1 or X3.2 – X3.1.

When the INV is disconnected from the power supply (no DC supply), a fault is signalled!

The remote signals are designed for safe isolation. The minimum load should not be below 12 V and 0.1 A.
