Timing relay modes
Time range
Variable values as time setpoint (I7, I8, I11, I12, actual value
T1 to T16, C1 to C16)
Parameters Switch function
X Switch with on-delay
?X Switch with on-delay and random time range
â Switch with off-delay
?â Switch with off-delay and random time range
Xâ On- and off-delayed, two time setpoints
?Xâ On- and off-delayed switching with random time, 2 time setpoints
ü Single-pulse switching
Ü Flash switching, mark-to-space ratio = 1:1, 2 time setpoints
Ü Flash switching, mark-to-space ratio k 1:1, 2 time setpoints
Parameters Time range and setpoint time Resolution
S 00.000 Seconds: 0.00 to 99.99 s 10 ms
M:S 00:00 Minutes: Seconds 00:00 to 99:59 1s
H:M 00:00 Hours: Minutes, 00:00 to 99:59 1 min.
h
Minimum time setting:
If a time value is less than the logic relay’s cycle time, the
elapsed time will not be recognised until the next cycle.
This may cause unforeseeable switching states.
h
If the value of the variable is greater than the maximum
permissible value of the configured time range, the
maximum value of the time range will be used as the
setpoint.
