Operating Instructions
The Centronic UnitControl UC42 and Centronic UnitControl UC45 are relay con-
trols which can be used in a variety of applications. These controllers are used to
operate a tubular drive with mechanical or electronic limit switches (without radio
receiver), as well as to operate other sequential phase controls. The UC42 can
also be used in the low voltage range as the outputs can optionally be isolated.
(floating outputs)
The unit is generally installed in the junction box next to the drive. Alternatively, it
can also be installed in a deep distribution circuit-breaker box (with a depth of at
least 60 mm over its entire area) behind an Up/Down switch. Wiring is effected
according to the wiring diagram.
The UC45 is to be mounted in a cable duct with an integrated top-hat rail system
or inside a distribution box. Wiring must be carried out in accordance with the ter-
minal diagram.
The individual command is executed as a touch control command (duration of
command < 1 sec.) or as a self-locking command (duration of command > 1
sec.).
In conjunction with blinds, touch control commands are executed as reversing
commands. The individual command is triggered by a standard commercial serial
switch. The individual command operates in increments of 3 minutes running
time.
The central command is executed in dead man's mode. Triggering occurs via
controls connected in series, such as programme timers, sun and wind units etc.
The connection of an additional superordinate UC42/UC45 controller allows the
central command to be executed in automatic mode. It is also possible to form
various groups by connecting further UC42/UC45 controllers.
Incoming commands are processed in the following order:
1. UP central command
2. DOWN central command
3. UP individual command
4. DOWN individual command
