High-Voltage Detection (H); Remote Control (R); Overload Detection (D) - Simco-Ion A Unit Bedienungsanleitung

6.2.2 High-voltage detection (H)

The "H" option (high-voltage alarm) is equipped with a relay that switches if the high voltage
fails. In this way an alarm signal can be triggered. This can be a lamp or a buzzer, for instance.
The contacts are two-pole make or break contacts.
The contact rating is 5 A.-240 V AC; 5 A-28 V DC.
1. Feed the wiring through the gland and lay it as far as possible from the HV terminal block.
Use the nylon clamp to guide the cable along the HV terminal block.
2. Connect the wiring to the terminal block X2.
The terminal contacts depend on your switching (switching on or off).
The contacts are drawn in alarm position.

6.2.3 Remote Control (R)

You can switch the power unit on and off from a distance with a potential free contact.
This may be a PLC contact or a switch/relay.
The contact must be able to switch at least 20 VDC/100 mA
1 Remove the interconnection of terminal block X3.
2 Feed the wiring through the gland and lay it as far as possible from the HV terminal block.
Use the nylon clamp to guide the cable along the HV terminal block.
3 Connect the wiring to terminal block X3.
When this option is not used, the interconnection of terminal block X3 must always be in place.

6.2.4 Overload detection (D)

The "D" option is an electronic circuit (detection circuit) that automatically switches off the built-
in transformer when the output current is too high.
- If conductive material falls onto the emitter points in directly connected anti-static bars, a
spark could flash over via the material to the earthed housing, leading to a risk of ignition in
the material to be discharged. The spark-over causes the power unit to overload and the
high voltage is switched off.
- When the total load of the power unit (number of bars + length of connected cables) is too
high, the power unit will become overloaded and the high voltage will also be switched off.
After tracing and eliminating the cause of the spark-over, the high voltage can be switched on
again by switching the power unit back on.
