NOVATEK-ELECTRO REV-201М
This present manual contains necessary information about application, main operation principles and
adjustment setting for the two-channel electronic time delay relay REV-201M (hereinafter REV-201М).
1 GENERAL DESCRIPTION AND OPERATION
1.1 APPLICATION
REV-201M is designed for the commutation of electrical circuits of 240V 50Hz AC as well as 24 –100V DC
electrical circuits with the adjustable time delay setting.
The relayhas two channels and can be operated by one of seven operation algorithms that the user specifies:
-Turn ON time delay relay;
-Pulse relay 1;
-Intermittent relay 1;
-Operation relay *.
-Pulse relay 2;
-Intermittent relay 2;
-Off-delay relay.
* REV-201M could be used as the relay of pre-starting signalization for the machinery that require to announce
that some mechanism or machinery will soon take a start to make people aware of this and get away from the risky
zones. Widely used for steel plants, heavy machinery, cranes and construction mechanisms as well as mining
companies for the technological stuff safety.
Time delay setting for each channel starts from the moment of the power supply given to the corresponding
channel. REV-201M allows to provide 2 modes of operation:
Mode 1. Independent operation of channels. To each of two channels power supply is given independently
and thus each channel starts the countdown from the moment the power supply is given. This is the mode when 2
independent time relays are functioning in one compact case housing (2 time delay relays in one case).
Mode 2. Parallel operation of the channels. To each of two channels the power supply is applied
simultaneously. Thus the time countdown on each channel starts at the same time and comes one and the same input
power supply. Triggering time corresponds to the user-adjusted settings for each of the channels. So the REV-201M in
this mode operates like one time delay relay with 2 output contacts that have the same or different time settings.
ATTENTION!!! The power supply of both channels must necessarily have common neutral.

NOVATEK-ELECTRO REV-201М
REV-201M complies with requirements: IEC 60947-1:2004, ІDТ; ІEC 60947-6-2:1992, ІDT;
IEC 61000-4-2:2001, IDT; CISPR 11:2004, IDT
Pollutants in the amount, which is not to exceed the maximum permissible concentration are none
1.3.2 Front panel view and outer dimensions are shown on figure 1.
1.3.3 REV-201M operation algorithms.
-Energized (Turned ON) state of the REV-201M corresponds the closed position of the output terminals 1-2
(Channel 1) and 4-5 terminals (Channel 2). Thus the terminals 2-3 (Channel 1) and terminals 5-6 (Channel 2) are
open when the REV-201M turned ON.
-Deenergized (Turned OFF) state of the REV-201M is when terminals 1-2 (Channel 1) and terminals 4-5
(Channel 2) are open. And accordingly when the REV-201M is in OFF state –then terminals 2-3 (Channel 1)
and terminals 5-6 (Channel 2) are closed.
-Initialization time delay. After the power supply is given to the input terminals of the REV-201M with the initially
preset Zero time delay settings REV-201M turns ON not momentarily but within the time of approximately 250
milliseconds. This happens due to smooth voltage increase on the power supply source of REV-201M.
1.3.3.1 “Turn ON time delay”
Figure 2 –The working algorithm of relay “Turn ON time delay”
Timing countdown on each channel starts from the moment when the power supply source is applied to the
input terminals «L1-N»,(Channel 1); «L2-N», (Channel 2). Time delay setting is selected using the knobs of
potentiometers 3, 5, 10, 12 (figure 1). Each channel has two adjustable knobs: Т1and Т2. Time delay for the output
contacts triggering of is determined as the sum of the values adjusted by both knobs (T1 + T2) for each channel
separately.
When the power supply is present –GREEN LED starts glowing and timing countdown begins. After the expiry
of time delay interval –RED LED turns on and the output contacts change the position to the ON state.
1.3.3.2 “Impulse 1” operation mode
Figure 3 –The working algorithm of relay “Impulse 1”
Time counting on each of the channels starts from the moment the power is applied to the terminals «L1-N»,
(Channel 1); «L2-N», (Channel 2). Each channel has two adjustments T1 and T2.
When the power supply is given –on the channel GREEN LED starts glowing and countdown begins. Time
delay intervals are adjusted using the knobs 5and 10 (Figure 1.) in the diapason T2 for the Channel 1 and Channel
2 respectively –pause time.
After the turn ON time delay expiry REV-201M turns ON for the time determined by the knobs 3and 12 (Figure
1) in the diapason T1 –LED indicator change the color to RED.
When the Turn ON time interval comes to an end REV-201M turns OFF the load and REV-201M switches to the
idle mode. LED color indicator changes to GREEN. A relay working cycle is restarted after recurrent de-energizing
and reenergizing the voltage supply.

1.2.3.3 “Intermittent 1” operation mode
In the figure 4 there is represented the working algorithm of relay " Intermittent 1”.
Figure 4 –The working algorithm of relay “Intermittent 1”
Time counting on each channel starts from the moment of power supply to the terminals «L1-N» (Channel 1);
«L2-N» (Channel 2). Each channel has two adjustments T1 and T2.
When the power supply is given to channel then the time reading T1 starts, adjusted by the knobs of
potentiometers 3, 12 (figure 1) for the 1-st and the 2-nd channels correspondently –time of pause. at this moment
GREEN LED indicator glows and the power load is turned OFF.
After the termination of this time interval (T1) power load turns ON and starts the timing countdown of another
interval (T2) that is adjusted by lower potentiometer knob 5, 10 (figure 1), for the 1-st and the 2-nd channels
correspondently –time of work and this is indicated with the RED LED indicator.
After the termination of the T2 timing countdown REV-201M turns OFF the power load and the LED indicator
changes to GREEN. From this moment new countdown basing the T1 timing starts and the process keep on
working in cycle mode in this way further.
Note –if the time interval of potentiometer Т2is equal to zero, the load relay will not switch over.
1.3.3.4 Control (pre-starting signalization)operation function
Figure 5 –The working algorithm of relay Control (pre-starting signalization)
ATTENTION! For the proper operation of REV-201M it should be connected in accordance with the
parallel channels operation –Mode 2 (for details kindly see paragraph 1.1. Application).
After the power supply is given to the input terminals REV-201M turns ON the power load for the Channel 1 –
simultaneously RED LED (Channel 1) and GREEN LED (Channel 2) indicator starts glowing –this indicates about
the preliminary signalization with the fixed time delay of 10 seconds.
After this interval the output relay of the “Channel 1” turns OFF for the fixed time of 30 seconds –this is
indicated by GREEN LED glowing on the “Channel 1”.
After the expiration of the pause for the “Channel 1” GREEN LED change the color to RED –second
announcement signal with the time of 30 seconds;
After the end of the second announcement signal the output relay of the “Channel” 1 turns OFF, LED changes
from RED to GREEN and the output relay of the “Channel 2” turns ON. At the same time GREEN LED of the
“Channel 2” change the color to RED and switches to IDLE state.
If you want to restart the algorithm –you will have to turn OFF the power supply and turn it ON afterwards.

NOVATEK-ELECTRO REV-201М
ATTENTION!!!
-In this mode of operation time adjustment knobs (T1 and T2) as well as the DIP switched for the time
ranges (D1 and D2) doesn’t function. All timing frames and intervals are preprogrammed and fixed. On special
customer request for the algorithm “START-PAUSE-START” it’s possible to change the timing intervals and
delays as per requirement
-REV-201M has internally preprogrammed block that doesn’t allow to turn ON the power load on Channel 2
until output contacts of Channel 1 are being closed (ON).
1.3.3.5 “Impulse 2”.
In the figure 6 there is represented the working algorithm of relay "Impulse 2”.
Figure 6–The working algorithm of relay "Impulse 2”
Time counting on each channel begins from the moment of power supply to the terminals «L1-N» (channel 1)
and «L2-N»(channel 2). The time delay is adjusted by the potentiometer knobs 3,5,10,12 (figure 1). Each channel
has two time setting adjustments T1 and T2. The channel cutting off delay is defined by sum of delays arranged by
two potentiometers (T1 + T2).
At power supply on the channel there switches the load relay on, a red LED of this channel is on and the time
reading begins T1 + T2. After delay time period the load relay switches off, the LED changes the light to green and
the relay turns in standby mode.
The restart of relay is made after de-energizing and energizing again of power supply.
1.3.3.6 Intermittent 2
In the figure 7 is resulted the working algorithm of relay “Intermittent 2”
”.
Figure 7–The working algorithm of relay “Intermittent 2”
Time reading on each channel begins from the moment of power supply to the terminals «L1-N» (channel 1) and
«L2-N» (channel 2). Each channel has two setting adjustments T1 иT2.
At energizing the power supply to the channel the load relay switches on and the time reading T1 starts, adjusted
by the knobs of potentiometers 12, 3 (figure 1) for the 1-st and 2-nd channels correspondently –time of work. The
red LED of the channel is on.
After the end of delay time period T1, the load relay switches off and the time reading T2 begins, arranged by
potentiometers knobs 5, 10 (figure 1) for the 1-st and the 2-nd channels correspondently –time of pause. The LED
of the channel changes the light to green color.
After the end of delay time period T2, the load relay switches on, the LED changes color to the red one and the
cycle of relay work is restarted (the delay time reading Т1 begins and so on).

Note –if the time interval of potentiometer Т1 is equal to zero, the load relay will not switch over.
1.3.3.7 Turn-off Delay
Figure 8 shows the relay operation algorithm for “Turn-off Delay”.
Figure 8 –The working algorithm of relay “Turn-off Delay”
After voltage supplies to the second channel, the green LED of the second channel lights up and the relay
switches to the standby mode.
When voltage supplies to the first channel, the green LED of the first channel lights up and timing of T1 + T2 of
the first channel is started.
Upon completion of time-delay the load relay of the second channel is activated, LED of the second channel
changes its color to red and the relay switches to standby mode.
In case of power failure in the first channel, the green LED of the first channel is off and timing of T1 + T2 of the
second channel is started.
Upon completion of time-delay the load relay of the second channel is disabled, LED of the second channel
changes its color to green and the relay switches to standby mode.
Note: In this mode, the supply voltage of the second channel is used as the main power supply for the
relay and the power input of the first channel is used as the control signal.
2 GENERAL USE AND APPLICATION
2.1 FIRST START UP PREPARATIONS
ATTENTION! All settings and adjustments of REV-201M should be made on deenergized device.
All wiring or cable connections (disconnections) to the REV-201M must be necessarily made on fully deenergized
device.
Adjustment should be made in the following sequence:
-Setting the operation algorithm
-Setting of timing parameters and delays
IMPORTANT NOTICES:
-When changing the operation algorithm it’s necessary to take into account that newly set up algorithm will
take effect only after full deenergization of the REV-201M (not less then 1 second), input terminals with
the subsequent turning ON of the device.
-After changing the time setting of the relay being energized it is necessary to note that a new time setting
will be effective only since the next cycle of relay work.
