Recommended Option: Pump Protection Limit
The Pump Protection Limit adds significant protection to the
PumpSmart PS200 system. With the pump protection limit
enabled, the PS200 system will be able to provide dry run (loss of,
or blocked suction) protection in pressure and flow control. It will
also be able to provide run-out flow protection when in pressure
control mode.
The pump protection limit works by identifying conditions where
the pump is unable to meet the protection limit when at
maximum speed.
The first step in enabling the Pump Protection function is to select
how you would prefer PumpSmart to respond if the protection
limit conditions occur. There are three options:
1.
ALARM & CONTROL [Recommended]- In this response,
PumpSmart will issue a warning and then either shut down or
reduce speed depending upon your settings. These settings
may be found in the OPTIONS & FEATURES section under
MINIMUM SPEED OPTIONS.
2.
ALARM only - In this response, PumpSmart will simply issue
an alarm/warning, but continue to operate. The alarm only
mode may result in damage to the pump if a protection limit
fault occurs and no manual intervention is taken.
3.
DISABLED (Default Setting) - In this response, there is no
protection limit functionality. If a closed suction valve (or
similar) condition exists, there may be damage to the pump,
and there will be no alarm warning the user.
