NOVATEK-ELECTRO
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”.

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.
