Connection to entries
A single contact can be used for running products either
up or down.
A set of two contacts can be used for running products
both up and down with variable stops.
A change-over contact can also be used for running prod-
ucts both up and down but stops are not possible.
Contact requirements
Dry contacts with a maximum resistance of 100 Ω can
be used. A current of 5-10 mA at approx 10 V d.c. runs
through the contact.
Contacts with a pulse signal can also be used if the dura-
tion of the pulse is longer than 100 ms.
Note: The operation of the interface/repeater unit can
only be stopped by switching off the mains power.
