REV-225

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.

Harmful substances in quantities exceeding the maximum permissible concentrations are not available.

1 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.

1.1 REV-225 visual appearance and overall dimensions

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 temperature: 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.).

3. INTENDED USE

3.1. Preparation for operation

3.1.1. Preparation for connection:

– Unpack the product (we recommend to keep the original packing for the entire warranty period of the product
operation);

– Check the product for damage after transportation; in case of such damages detection, contact the supplier or
manufacturer;

– Carefully study the Operating Manual (pay special attention to the connection diagram to power the device);

– If you have any questions regarding the installation of the product, please contact the manufacturer by

telephone number indicated at the end of this Operating Manual.

3.1.2 Device connection

ATTENTION!

OUTPUT CONTACTS OF LOAD RELAY ARE NOT DESIGNED FOR LOAD COMMUTATION IN CASE OF
SHORT CIRCUITS. THEREFORE THEY SHOULD BE PROTECTED BY AUTOMATIC CIRCUIT BREAKERS
(FUSES) WITH TRIPPING CURRENT NOT EXCEEDING 16 A OF CLASS B.

ATTENTION! ALL CONNECTIONS MUST BE PERFORMED WHEN THE PRODUCT IS DE-ENERGIZED.

Error when performing the installation works may damage the product and connected devices.

To ensure the reliability of electrical connections you should use flexible (stranded) wires with insulation for voltage
of no less than 450 V, the ends of which it is necessary to be striped of insulation for 5±0.5 mm and tightened with
bootlaces. The cross-section of the wire for connecting the protected equipment depends on the current (power) of

the load. For example, at current 10A - is not less 1 mm2.

Wires fastening should exclude mechanical damage, twisting and abrasion of the wire insulation.

IT IS NOT ALLOWED TO LEAVE EXPOSED PORTIONS OF WIRE PROTRUDING BEYOND THE TERMINAL
BLOCK.

For reliable contact it is necessary to perform tightening of screws of removable terminal block with the force
specified in Table 1.

When reducing the tightening torque, the junction point is heated, terminal block may be melted and wire cane burn. If
you increase the tightening torque, it is possible to have thread failure of terminal block screws or the compression of the
connected wires.

To improve operational properties of the device it is recommended to install the fuse or its analogue for
1 A current in power supply circuit for REV-225.

3.1.2.1 Connect REV-225 according to the diagram indicated in Fig. 2.

ATTENTION! LOAD TERMINALS ARE DESIGNED FOR MAXIMUM VOLTAGE OF 300 V;
