Assembly and Operating Instructions
Install the control unit so that the operator controls are readily accessible. The cover of the housing with the 3-way pushbutton
switch has to be removed for installation purposes.
The unit is mounted on the wall with four 4 mm dia. screws (max. head dia. 8 mm) using the four fastening holes, which also
take the screws to fit the cover, in accordance with the dimensioned drawing on the bottom of the housing.
If necessary, you can fit more cable glands for sensor cables and indicating cables.
Attention
When removing housing knockouts in order to fit more cable glands, take care not to damage any compo-
nents on the control boards or the housing itself. Only fit sealing cable glands which ensure the housing
has the correct degree of protection.
When refitting the cover, ensure that the seal and the seal groove are clean and that the cover is mounted
properly.
Tighten up the housing cover screws carefully. Only then will the IP 65 degree of housing protection re-
main intact.
Installing the control unit
The S80 door control system for drives with mechanical limit switching can be con-
verted/upgraded by changing plug-in control cards. The following control cards
are available:
•
MLS Basic Card
•
MLS Professional Card
Before changing a control card, disconnect the entire door control unit from the
mains and open the cover of the control box.
Attention
The regulations for handling elements with an electrostatic risk
must be complied with. The MLS Professional Card may only be
used in combination with a safety edge. When delivered, safety
devices may be bridged. When changing from the MLS Basic Card
to the MLS Professional Card, always ensure that no non-permis-
sible bridging exists or, if such bridging does exist, ensure that it
is removed.
Carefully pull out the control card connected to slot
J3/J4
and insert the new con-
trol card at slot
J3/J4
on the
S80
motherboard as illustrated opposite. With the
MLS Basic Card ensure that the board is the right way round.
