Wiring
The ICS-6-OEM is a versatile interlock system and there are a variety of ways in which it can be used.
Be sure you know which configuration you require before you attempt to wire the unit.

6.1 ICS-6-OEM Inputs
Mechanical Interlock Switches
Up to six door/cover interlock switches may be directly wired to the ICS-6-OEM. By making external
connections, more switches can be added and arranged in groups.
The interlock switches are wired to the terminals labelled INPUT 1 through to INPUT 6. Each
interlock switch should have two safety contacts which are closed when the door is closed. Some
door contacts such as Lasermet’s IS-MECH switches have an additional monitor contact which closes
when the door is opened. This is not used in ICS-6-OEM.
A 4-way terminal block is provided for each door interlock switch. One of the safety contacts, which
are closed when the door is closed, is wired to the ‘A’ terminals. The
other safety contact is wired to
the ‘B’ terminals.
The example diagram below shows a system with two doors wired for ISO 13849 performance level
‘e’. Each door has two switches.
