Single device operation – special aspects
Interlock output inhibit
TopCon TC.GSS power supplies have a feature for rapidly inhibiting the
output using an interlock signal.
All external EMERGENCY STOP contacts must close the interlock circuit
for operation to be possible.

-1- External EMERGENCY STOP button with internal voltage source.
-2- External EMERGENCY STOP switch with external voltage source.
With interrupted interlock circuit
The power stage is switched off directly
via a hardware link.
The controller remains switched on.
The device changes to the state: “Error”.
To work using the TC.GSS power supply (or a system with TopCon modules),
check that the interlock circuit is actually closed.
Ensure that the correct dummy plug has been used for the termination of the
interface X101.
For further information see chapter 4.3.2.1, page 46.
The description of the interlock circuit for multi-unit systems is different due to
the utilisation of the interface X102 for the different devices in the system.
For further information see Fig. 31, Seite 60.
4.3.4. Interlock circuit with X101 and X105
Ring structure of the interlock circuit
The interlock circuit makes it possible to setup a safety infrastructure.
The basis for the function is an electrical ring structure that must be
closed for operation.
Safety elements -2- (e.g. EMERGENCY STOP buttons) can interrupt
the ring and as a result switch off the TopCon power supply.
For higher safety requirements, e.g. safety class 1, the option: ISR (Integrated
Safety Relay) is available.
For further information see chapter 5.2.2, Seite 77.
