8.4 PulsaGuard Pump Protection
PulsaGuard is designed to turn your pump off when running in dangerous conditions. These conditions are
user configurable and can be easily modified to meet each application.
When flow meter feedback is being provided, PulsaGuard will turn off your motor if a low flow set point is
crossed for more than 10 seconds. This will protect the pump in under-loaded or overloaded conditions, which
would cause the flow to fall below the user’s acceptable limit. The MPC VECTOR will also trigger an alarm
condition if the flow set point cannot be reached for some reason. This alarm will be displayed on the MPC
MPC VECTOR display but will not shut the motor off. If the MPC VECTOR is operating without flow meter
feedback PulsaGuard can read the motor current and shut off the pump if the current drops below the shut off
level and stays under that level for 10 seconds, effectively protecting equipment from under-loaded conditions.
The PulsaGuard pump protection may be enabled and disabled as desired from the System Setup menus (see
section 8.4.2: PulsaGuard Enable/Disable). Note that once a calibration is performed the pump protection is
automatically enabled, you will not have to manually enable it.
