Section 5: Programming the Z-100 Controller
Diff Alarm Count:
This setting is only available on the 610F models
(F indicates Flow Switch). The PUMP ALARM
is triggered when the difference, DIFF, between
pump actuations signaled and flow switch closures
sensed exceeds the DIFF ALARM COUNT setting.
The DIFF is accumulated over a 24 hour period and
once exceeded will trigger the pump alarm. At the
end the 24 hour period, the DIFF will reset to zero.
Default is 10.
Alarm Sources:
Selecting Alarm Sources will open a sub-menu to
select the alarm sources in which to be notified. The
three alarm options are Battery Low, Solenoid, and
Pump Flow (610F only). The selected alarm will be
highlighted with an asterisk (*). Navigate to each
alarm in the list and press enter on the navigation
switch to select or deselect each option. If an alarm
source is activated, it will have a single line dash
(-) next to the alarm. Press the navigation switch
left to exit the sub-menu.
Battery Low:
The Battery Low alarm is an indication the battery
voltage is low and should be replaced. If enabled,
the Relay Output will be activated. The remaining
battery capacity is dependent on the settings and
ambient temperature the system is installed. The
more often the pump is actuated with ambient
temperatures approaching minimum or maximums
of the operating range will result in considerably
shorter battery capacity.
Solenoid:
The solenoid alarm is an indication the solenoid
fuse (F1), needs to be replaced.
A low supply voltage could also cause a solenoid
alarm. If replacing fuse (F1) does not remove the
solenoid alarm, verify supply voltage is within the
required operating range using the Battery Test
function.
NOTE: The battery test function can also be used
to verify external supply voltage.
If these steps do not remove the solenoid alarm,
please contact YZ System Tech Support for help.
Pump Alarm:
The PUMP alarm is triggered when the difference,
DIFF, between pump actuations signaled and flow
switch closures sensed exceeds the DIFF ALARM
COUNT setting in a 24 hour period.
