AUTO RESET
Reset Mode—Three (3) modes of resetting Fault Trips are
available:
0–Manual—Requires pressing Reset button on DIM,
pressing Reset button on the face of the S811+, or by
providing a signal to an Input Control Terminal configured
for this function (Terminal 4 default).
1–AUTO—The S811+ firmware attempts to clear any
active Fault Trips.
2–Powerup Reset—The S811+ will perform a Fault
Reset action after the unit has completed the initialization
process when 24 Vdc control power is applied. Fault trip
reset action then reverts to Manual
Auto Reset Delay Timer—When the Reset Mode is set to
one (1), the S811+ will automatically reset any fault or
warning after the reset delay time has expired and the
condition no longer is active. The delay timer will start as
soon as any fault is detected. If the fault is still present after
the delay time has expired, the reset protocol will remain
active to attempt to clear the fault trip condition. The delay
timer is user settable with a range of 0.1 (default)—600
seconds.
Auto Reset Count—A counter will log the number of
successful Reset attempts. The Auto Reset Count may be
observed in the Monitoring Menu. The Auto Reset Count will
reset to zero (0) with each power cycle of the 24 Vdc control
power.
Auto Reset Limit—The Auto Reset Limit is selected by the
user, up to a maximum of 10000 Auto Reset attempts. When
the maximum number of Auto Resets is attained, a Manual
Reset is then required. When a Manual Reset is performed,
the counter is set to zero (0). Setting this parameter to zero
(0) disables the counter function.
Auto Rest Mode, Auto Reset Delay, and Auto Reset Limit
parameters are located in the Soft Start Config. Menu.
FAULT WARNINGS
Fault Warnings do not require any reset action. The Fault
Warning indication in the DIM is discontinued when the Fault
Warning condition is no longer active.
