INTERLOCK TYPE: This parameter is displayed only when
TwisTorr 304 FS AG Rack Controller User Manual / 87-901-029-01
START/INTERLOCK: The pump is started if the
START/STOP input is activated and is stopped if the
START/STOP input is de-activated. The interlock input
must be constantly active (INTERLOCK TYPE parameter
= continuous) or may be active only at the time of
starting (INTERLOCK TYPE parameter = impulsive)
START/STOP LEVEL The START/STOP input acts as
only START command (active on the level) The
INTERLOCK input acts as STOP command (active on the
level).
In the case of concurrent activation of the two inputs,
the STOP command takes priority
START/STOP EDGE The START/STOP input acts as
START command (active on the edge)
The INTERLOCK input acts as STOP command (active
on the edge).
the previous parameter (START MODE) is equal to
START/INTERLOCK and permits selection of one of the
following two operating modes of the INTERLOCK input:
CONTINUOUS: the INTERLOCK input must be active
continuously so that the pump can be driven by the
controller. If, with the controller in start, the input
INTERLOCK is de-activated, the controller switches to
WAITING INTERLOCK status and interrupts driving of
the pump
IMPULSIVE: it is sufficient for the input to be active
when the START command is sent to the pump.
Subsequently, the input can also be de-activated. If the
interlock is not active when the pump is started, the
controller switches too WAITING INTERLOCK status.
