Status outputs and relays
The status outputs are used for remote diagnostics of the controller status or of the links of several controllers with one
another.
They are designed as freely available NPN-doped transistor circuits and they are floating.
With the status output
READY
the transistor circuit is switched through whenever the controller is connected to power
supply and switched on by its power switch closed.
The status output
ACTIVE
requires the same conditions for switching-through as "READY".
In addition, the channel must be energized, the transistor blocks in case of ACCUMULATION, OFF or STOP.
The status outputs as well as the external enabling inputs are to be wired via plug connector XS4.
The two relays have different functions.
K1 operates as a status relay parallel to the
ACTIVE
status output.
K2 serves either for a blowing air switch-off delay (4 sec.) or for cycle monitoring of one of the two sensor channels.
Connections and cable entry are on the right-hand side of the controller with the terminal block behind the panel.
