Alarm Output A1:
Alarm 1 ( Temperature- or heater current monitoring alarm A1 for all zones)
Alarm Output A2:
Alarm 2 ( Temperature- or heater current monitoring alarm A2 for all zones)
Setpoint Controlling:
K1: open
=
Setpoint 1 (SP1) valid
K1: closed
=
Setpoint 2 (SP2) valid, for all zones
Adjustment lock (LOC):
K2: open
=
Adjustment lock only via „software code“ (see parameter: LOC)
K2: closed
=
Adjustment locked according to the choosen „software code“.
Setpoint changing:
K3: open
=
individual setpoint adjustment for each zone
K3: closed
=
if setpoint has been changed in one zone,
this new setpoint is valid (will be overtaken) for all other zones automatically.
CAN-Interface, (Option):
K4: open
=
CAN: „operational“. Operation only with CANopen protocoll.
K4: closed
=
CAN: „operational“ always active.
K4 must be closed, if the instrument is equipped with a CAN-interface but not used.
