PUMP PROTECTION
The SWO has numerous safety features built into the system to protect the
pumps from damage. Some of these shut down all operation and some are designed to
halt operations until the system can stabilise. The user determines the selection of each
of these.

High Level Shutdown
If the system level goes over the High Level setting for a period of time, the SWORDFISH
+ will shutdown the system until manually reset.
There is the option to allow a number of automatic restarts after this shutdown.
There are 0-250 restarts
possible and are set in the “High level Restarts” screen within
the TUNING menu pending tank fill / empty option setting.
Low Level Shutdown
If the system level drops under the specified Low Level setting for a period of time the
SWO will shutdown the system until manually reset.
There is the option to allow a number of automatic restarts after this shutdown.
There are 0-250 restarts possible and are set in
the “Lo Level Restarts” screen within the
TUNING menu pending tank fill / empty option setting.
Individual Pump Protection
SWO has inputs for each pump to allow for individual pump protection. In the
event of a pump going into a fault condition the input for that pump should close. This will
shut down the pump after the time set by the Input Delay Timer.
The pump will automatically restart when the Input contact is opened.
This protection is ideal for the following pump protection sensors:
•
Temperature probes
•
Loss of prime pressure switches
•
Thermal Overload
•
Thermistor
ALL FAULTS CAN BE REMOTELY RESET FROM THE “RESET INPUT”
