Optionals - Simco ECM 30 Notice D'utilisation

8. Options
8.1. Summary
Switching on/off (remote on/off) and setting the output voltage are functions that can be remote-
controlled. Remote read out of the output voltage and output current is also possible. 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 signal / data cable.
Sub-D connector layout (rear panel view).
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 connection.

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 12VDC (10 mA) is
required. 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 very much on
the connected load.
If the remote on/off function is used, the [ON/OFF] switch should be in the [ON] position.
If remote on/off is used, the [RUN] key can be used to activate the output voltage manually for
testing purposes.
