EG 270
Working principle :
The EG 270 is a time switch for the
automatic control of electrical loads.
It is fully programmable with a maximum
of 20 program steps to be divided bet-
ween the two channels. Each program
step can be applied to one or several
days, maximising the use of each memo-
ry location.
The front cover is sealable preventing
unauthorised access after completion of
programming.
Warning : at the beginning of use, please
reset the device in order to clear the
memory before programming.
This is achieved by using a pen to push
the reset button.

The Hager EG 270 is a 2-channel time switch with a weekly cycle, designed for the automatic control of electrical loads. It offers full programmability with a maximum of 20 program steps, which can be distributed across its two channels. Each program step can be applied to one or several days of the week, optimizing memory usage. The device features a sealable front cover to prevent unauthorized access after programming is complete.

Function Description:

The EG 270 allows users to set specific times for electrical loads to turn ON or OFF. It supports two independent channels (A and B), each with its own programming. The device operates in several modes:

• Time Setting (L): Used to set the current time and day.
• Programming Channel A (A): Allows users to define ON/OFF switching times and assign them to specific days for channel A.
• Programming Channel B (B): Similar to channel A, but for channel B.
• Running Auto Mode (auto): The default operating mode where the device executes the programmed schedule. It displays the current time, day, and the status of both channels. No modifications can be made in this mode.
• Manual Override (manu): Provides options for temporary or permanent manual control over the outputs, overriding the programmed schedule.

Important Technical Specifications:

• Electrical Characteristics:
  • Supply Voltage: 230V +10/-15% 50Hz
  • Outputs: 2 changeover contacts
