The present Operating Manual is intended for familiarization with the design, safety requirements, operation and
maintenance procedure of the astronomical time relay
REV-225
(hereinafter referred to as “the device”, “
REV-225
”).
REV-225
complies with the requirements of the following international standards:
EN 60947-1; EN 60947-6-2; EN 55011; IEC 61000-4-2.

APPLICATION
REV-225 is a microprocessor-based device designed to be operated in automatic control systems with reference
to the astronomical time (sunrise / sunset).
The sunrise and sunset times are automatically calculated by REV-225 based on the coordinates entered and
the current time that allows controlling the lighting without using the external sensors.
There is the program setting that allows switching off the load at night (night break).
The built-in power supply unit (lithium battery) provides keeping the operation of the real-time clock and the
device in the event of mains power supply failure.
Features of REV-225:
–
Digital time relay with astronomical program;
–
The power supply unit is designed to operate for 3 years (lithium battery);
–
Sealable front panel cover;
–
Adjustment using four buttons;
–
Automatic switching to summer / winter time;
–
Liquid crystal display;
–
Operation mode for days off;
–
One channel;
–
Double module mounted on 35 mm DIN rail.

REV-225 visual appearance and overall dimensions are shown at figure 1.
1.2
Operating Conditions
REV-225
is designed for operation in the following conditions:
–
Ambient t
emperature: from minus 35 to +55°С;
–
Atmospheric pressure: from 84 to 106.7 kPa;
–
Relative air humidity (at temperature of +40°С) no more 50%.
If the temperature of the device after transportation or storage is different from the temperature of the
environment in which its operation is assumed, then before connecting to the mains keep the unit in operation
conditions for two hours (because on the unit elements condensation may be available).
ATTENTION!
The unit
is not intended
for use:
- in conditions of significant vibration and shocks;
- in high humidity conditions;
- in corrosion environments with content in the air of acids, alkalis, etc., as well as severe contamination (grease,
oil, dust, etc.).
