“
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 Т2 is 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 se
cond 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.
