Safety warnings
Attention: Electrical equipment must be installed
and fitted by qualified electricians.
Failure to observe any of the installation
instructions may result in irreparable damage, in
fire and in other hazards. To prevent electric
shocks, disconnect the mains supply (by cutting
out the circuit breaker) before working on the load
or on the device itself.
Function
The RolloTec
®
cut-off relay is installed between the
control element and the motors when two
conventional drive motors are to be controlled from
one control element. Among the control elements that
can be used are all RolloTec
®
controls, EIB controls
and blind/shutter switches or pushbuttons.
The instructions of the motor manufacturers
concerning the switch-over time at changes of the
running direction must be observed to avoid
damage to the motors.
If more than 2 motors are to be connected in parallel,
several cut-off relays can be used. In this case, all
blind/shutters are controlled centrally from one control
element (see fig.
A
).
Do not connect more than 6-8 motors at maximum to
one circuit breaker (observe the current rating). In all
other cases, distribute the load over more than one
circuit breaker.
If the blinds/shutters are to be controlled from more
than one control element, this can only be
accomplished with the extension units for the
RolloTec
®
inserts (see fig.
B
).
Important
•
It is not permitted to connect 2 control
elements to a single cut-off relay.
Simultaneous actuation of different running
directions would inevitably cause irreparable
damage to the motors or the control elements.
•
Use only blind or shutter motors equipped
with limit switches (mechanical or electronic).
Fitting
Rail-mounted cut-off relay REG
Install the cut-off relay REG only in distributions or
control cabinets on a 35 mm DIN rail.
Flush- or surface-mounted cut-off relays UP/AP
Install the cut-off relay UP/AP in a flush-mounting box
with blind-plate cover or behind a RolloTec
®
insert or
in a separate distribution box. The type of protection
achieved is dependent on the distribution box used.
