Figure 68: TOR relay in size 1 devices
The RUN relay (control signal terminal 23/24 sizes 2, 3 and 4 only) closes
together with the start command at control signal teA1. The start
ramp (t-Start) is enabled around 100 ms later. This makes it possible to
switch an optional mains contactor on and off via the RUN relay. If there is no
voltage present at the power section by this time of 100 ms, the DS7 soft
starter switches off with the “phase failure” fault signal.
The TOR relay (control signal terminals 13/14, or 13/-A2 in the case of size 1)
will be switched on after the set t-Start time elapses (the contact will close).
The TOR contact will open again (the relay will be de-energized) if the start
command on control signal teA1 is turned off or if the DS7 soft
starter detects a fault.
→
Soft starters DS7 of the size 1 (up to 12 A) have no RUN / READY
relay.
The TOR relay in this size has different terminal designations
and has the same reference potential (-A2) as the control
voltage.
