Function Conditions
Resulting Action of Overfeed Timer
Manually Holding Relay Operation (when outputs are held)
Off relay held in “off”
Overfeed timer
was off
Overfeed timer remains off. After you change back to
the “active” status from the HOLD mode, the overfeed
timer will remain off until the measured value (or a
value you simulate) causes the relay to turn on.
On relay held in “on”
Overfeed timer
was counting
Overfeed timer continues its “count down” until it
turns the relay off. If you release HOLD before the
timer “times out,” the timer continues its “count down”
until it turns the relay off or the timer automatically
resets when the measured value (or a value you
simulate) causes the relay to turn off. If you release
HOLD after the timer has “timed out,” it must be
manually reset (PART THREE, Section 6.4).
On relay held in “on”
Overfeed timer
was timed out
Overfeed timer remains off which keeps the relay
turned off. You must manually reset the timer (PART
THREE, Section 6.4).
Manually Testing Relay Operation (using TEST/MAINT menu screens)
Off relay is
changed to “on”
Overfeed timer
was off
Overfeed timer starts its “count down” until it turns the
relay off. After you change the “on” relay back to “off,”
the overfeed timer automatically resets.
On relay is
changed to “off”
Overfeed timer
was counting
Overfeed timer automatically resets. After you
change the “off” relay back to “on,” the overfeed timer
starts its “count down” until it turns the relay off, or
On relay is
changed to “off”
Overfeed timer
was timed out
the timer automatically resets again when the meas-
ured value (or a value you simulate) causes the relay
to turn off.
Operating a Relay By Simulating a Value (using TEST/MAINT menu screens)
Off relay is turned
“on” by simulated value
Overfeed timer
was off
Overfeed timer starts its “count down” until it turns the
relay off. After you change the “on” relay back to “off,”
the overfeed timer automatically resets.
On relay is turned
“off” by simulated value
Overfeed timer
was counting
Overfeed timer automatically resets. After you
change the “off” relay back to “on,” the overfeed timer
starts its “count down” until it turns the relay off, or
On relay is turned
“off” by simulation value
Overfeed timer
was timed out
the timer automatically resets again when the meas-
ured value (or a value you simulate) causes the relay
to turn off.
