Relay Timing
Definitions
D4 Delay time from the end of
HOLD
time until the
END OF WELD
or
ALARM
relay turns on.
This time is 25 ms or less in most cases. However, if the energy remaining in the capacitor
bank at the end of pulse 2 is greater than the energy required for Pulse 1 of the next weld,
the unit will discharge the capacitor bank to the proper energy level. The end of weld relay
will be delayed until the proper energy level is reached.
D5 Duration of the
END OF WELD
relay. This is from 100 to 125 ms.
D6 Delay time from the end of the weld pulse until the
OUT OF LIMITS
relay turns on. This time
ranges from 100 to 250 msec.
D7
Delay time from the end of
HOLD
time until the
COUNTER EXCEEDS LIMIT
relay turns On.
This is from 125 to 250 msec.
