Options; Switching On/Off (Remote On/Off) - Simco-Ion CM Medium Notice D'utilisation

8. Options

8.1. Summary
Switching on/off (remote on/off) and setting the output voltage are functions that can be
remotely controlled. A 25-pin Sub-D-connector has been fitted at the rear of the unit for this
purpose.
The options can be installed using low voltage / datacable.

Warning:
When carrying out work on the equipment: de-energise the equipment.
-
- Work on the equipment must be carried out by a skilled electrical engineer.
Only connect the specified voltages to the control circuits.
-
- Use only shielded cables and shielded Sub-D connectors for the connections.

8.2. Switching on/off (remote on/off)

8.2.1. Summary
This function switches the output voltage, not the mains voltage. A voltage of 12V (10mA) is
required to switch. This voltage is present on the Sub-D connector, but can also be supplied
externally. Mind the switching speed; the unit needs 60 ms to reach the maximum output
voltage from 0 kV. The time needed to reach 0 kV from the maximum output voltage depends
largely on the connected load.
When the remote on/off is used, a solder connection must be made on the SubD25 connector. If
remote on/off is used, the [RUN] key can be used to activate the output voltage manually for
testing purposes.
