5. AREA OF APPLICATION
The timer 1078-1 or 1078-2 is plugged on a solenoid valve
by means of an EN 175301-803 form A fixed connector.
The timer allows for controlling the activation/deactivation
cycle of the solenoid valve.
5.1. General description
5.1.1. Construction
The timer 1078-1 or 1078-2 is a class II control device and
a Type 1 action device (see EN 60730-1 standard).
The timer 1078-1 or 1078-2 is an electronic module enclosed
in a housing with a transparent cover, a cable gland and an
EN 175301-803 female fixed connector, form A, with seal.
The timer is attached to the solenoid valve by means of a
screw.
• The timer 1078-1 is connected to the power supply
through the cable gland, by means of a 3-pole terminal
block in the housing.
• The timer 1078-2 is connected to the power supply
through the cable gland, by means of a 5-pole terminal
block in the housing.
The timer energizes the solenoid valve.
The timer 1078-2 can be configured by means of a configu-
ration module 1077-2, inserted onto the 1078-2 in place of
