Hörmann slack cable switch for WA 300 and WA 400, with 500 mm round PUR cable

The slack cable switch monitors the tension of the cable from which the leaf of an industrial sectional door hangs. If the cable goes slack, for example when the door hits an obstacle while closing, the switch stops the operator. It is a safety device, so replace a damaged switch as soon as possible. The switch connects to the operator with a plug, so replacement is simple.

Which operators

• Hörmann WA 300 and WA 400 operators for industrial sectional doors.
• Requirement – the door must have a slack cable safety device; the switch alone does not replace it.

What to bear in mind before replacement

• Compare the cable length of the old switch. This part has a 500 mm cable.
• If a WA 400 operator fails, the fault may also be in the control; see the A 445 control unit.
• Leave work on an industrial door to a specialist.
