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.
