Equipment designation

B1 = SGS limit switch

F2 = Fuse ‘main hoist motor’

K3 = Contactor ‘Main lifting’

K4 = Contactor ‘Main lowering’

M2 = Main hoist motor

S1/S2 = Pushbutton lifting/lowering

S3 = Emergency limit switch lifting/lowering

U1 = MKA-2 contact evaluator

The SGS load link is plugged into position SGS on the PCB (SGS 1, SGS 2, PE).

The outgoing terminal connections are connected to the MKA-2 contact evaluator.

DR terminal SGS 1 on MKA terminal 2 and DR terminal SGS 2 on MKA terminal 3.

Plug the jumper behind the front plate of the MKA-2 into position 2, i.e. between the

pins in the middle and at the bottom.

(see also description of MGS/MKA-2 load detectors (206 689 44))

When SGS and MKA are used in combination, only the ‘overload cut-out’ function

can be used.

Only use contacts 23 - 24 of the MKA.
