*The connection of outputs 2-5 directly to the Power, without a load, is not
permitted. The connection of outputs 1 and 6 directly to the Ground, without a
load, is not permitted
The signals to be necessarily connected marked in the table in Italics
X1.1 Hea
The input can be used to switch off the heater, operated in pre-heat mode, by the
impulse of positive polarity (the input
Heater_off
- in that case has to be connected
to the Ground). The heater is stopped by the leading edge of the impulse. If the
heater is idle, positive impulse on this input cancels the program start of the heater,
programmed by CIP.
X1.2 Heater_off-
The input can be used to switch off the heater, operated in pre-heat mode, by the
impulse of negative polarity (the input
Hea
in that case has to be
connected to the Power). The heater is stopped by the leading edge of the impulse.
If the heater is idle, negative impulse on this input cancels startup of the heater,
programmed by CIP. This input is suitable for the most alarm systems and GSM-
modules connections in order to control the heater remotely.
X1.3 He
The input can be used to switch the heater on by the impulse of positive polarity
(the input
Heater_on
- in that case has to be connected to the Ground). The heater
is started by the leading edge of the impulse.
X1.4 Heater_on-
The input can be used to switch the heater on by the impulse of negative polarity
(the input
He
in that case has to be connected to the Power). The heater is
started by the leading edge of the impulse. This input is suitable for the most alarm
systems and GSM-modules connections in order to control the heater remotely.
