Intended use
-
Switching of electrothermal actuators for heaters or cooling ceilings
-
Installation in distribution boxes on DIN rail according to DIN EN 60715
Product characteristics
-
Switching operation or PWM operation
-
Actuators with characteristics opened or closed without power
-
Overload-protected, short circuit-protected
-
Protection against jamming valves
-
Forced position
-
Various setpoints for forced position or emergency operation in case of bus failure for
summer or winter
-
Cyclical monitoring of the input signals can be parameterized
-
Feedback via bus, e.g. in case of mains failure, overload or sensor failure
i
PWM operation: electrothermal actuators only have the positions "open" and "closed". In
PWM operation, switch-on and switch-off during the drive's cycle time achieves an almost
constant behaviour.
Overload protection
In order to protect the device and connected actuators, in case of overload the device
determines which output is involved and switches it off. Non-overloaded outputs continue to
work, which means that the rooms in question are still heated.
-
In case of major overloads the actuator initially switches all off the outputs
A1...A6
off.
-
In the case of more minor overloads the actuators switches output groups
A1...A3
and/or
A4...A6
off.
-
The actuator determines the overloaded output in up to 4 test cycles.
-
If in the event of only a minor overload it is not possible to unambiguously identify any
output as overloaded, then the actuator switches individual outputs off one after the other.
-
The overload can be reported to the bus for each output.
4 Information for electrically skilled persons
4.1 Fitting and electrical connection
DANGER!
Electrical shock when live parts are touched.
Electrical shocks can be fatal.
Before carrying out work on the device or load, disengage all the
corresponding circuit breakers. Cover up live parts in the working environment.
Fitting the device
Observe the temperature range. Ensure adequate cooling.
o
Mount device on DIN rail. Output terminals must be at the top.
