Alarms:
The X-Caliber has many built in self-protecting features and will indicate the various alarm conditions with the
following LED configurations.
Acknowledgement of the Alarms:
Once the X-Caliber has gone into an alarm condition, it will not automatically restart. To restore the X-Caliber to
normal operation, rectify the alarm condition, make sure the pump is primed, and press the on/off switch twice. An
alarm condition may also be acknowledged by turning the power to the pump off and then back on again. If the
alarm condition still exists, then the alarm must be acknowledged by pushing the on/off switch only. The pump will
resume normal operation if the alarm condition has been resolved.
Dry Run Alarm:
The X-Caliber will sense a dry run condition by monitoring the combination of input power, RPM, and system
pressure. Most probable cause of a dry run alarm is an empty water tank or a leak in the suction piping.
Under and Over Voltage Alarm:
The X-Caliber will recognize if it should operate on 12VDC or 24VDC on initial power up. The green “Power” LED
will flash once if the system is rated 12VDC or twice if the system is rated 24VDC. The pump will recognize when
the voltage is falling below its nominal range and revert to an “emergency” low power 300-watt mode. The blue
LED will flash continuously when the pump is in the emergency power mode. If the voltage continues to fall,
the pump will go into a low voltage alarm and turn off.
If the voltage exceeds the X-Calibers’ maximum rated input voltage, the pump will go into a high voltage alarm and
turn off. The voltage ranges for the normal, emergency, and alarm conditions for both 12VDC and 24VDC are
shown in the table below.
