II.2.2.2 Circuit selector:
External CS :
The DIAM CCR has two electrical interlock terminals,
terminal S1 and S2 , located at the right rear of the CCR,
which must be connected to the door contact and circuit
selector interlock.
When the CCR is used with a circuit selector, it must
be stopped about 100ms before the circuit is selected. This is
automatically done by the selector itself (Augier) by
connecting terminals S1 & S2 to the selector interlock
mechanism, or by remote control.
Operation without selectors:
The two terminals S1 & S2 must be short-circuited, (Strap
wired at delivery) in order to work without CS contact.
Operation with selectors:
The good practice, to select or un-select a way, is to do it at
null current. Thus, no overcurrent can appear and lamps remain protected. At the contrary, an instantaneous
short circuit (total or partial) of the load will create an instantaneous overcurrent proportional to the load
reduction, during the regulation time. These repeated overcurrents cause a reduction of the lifespan of lamps.
So, when used with a circuit selector, the regulator must be stopped 100ms approximately before changing a
circuit.
That can be carried out by the selector itself (Augier selector) by cabling terminals S1 and S2 with interlock
terminals of the selector, or by the monitoring system.
While S1/S2 are connected, the CCR shall be stopped if the selector box is opened, giving access to the H V
load connections.
