TSLM - M601 Operational & Install Manual

Start Interrupter Valve

The start interrupter valve regulates the fuel to the two torches and is used during the start process

and in anti-flameout operation. For older TSLM SN 5001-6200 units there are two ways to wire the

interrupter to the TSLM module – the normal way and the alternative way. On the newer TSLM (SN

7001 and up) units you must wire it the normal way. In the normal way the interrupter is activated

with a positive voltage on the valve’s pin A as shown below.

The alternative way on the other hand activates the interrupter valve by grounding pin V instead as

shown below.

Important:

For an older TSLM (SN 5001-6200) the unit needs to be configured to either the normal or

alternative interrupter setting. The SetView Software chapter explains how to do it. The

configuration property to be set is called ‘Alternative Interrupter Activation’. If you choose the

alternative circuit, this configuration property needs to be set to 1 instead of 0 as explained in the

Alternative Interrupter Activation setting.
