Function Features
Pump control – Control of two pumps
Pump limiting – For limiting max flow or power requirements
Duty sharing and alternation – Adjustable duty change period and bumpless transfer
Pump staging and destaging – Additional pumps are staged into operation to maintain setpoint and destaged when no longer required
Staggered pump start and stop – Prevents excessive current draw and reduce water surge or hammer
Manual control – Manual modes for system and pumps with 10 minute timeout to revert back to auto mode
System types – Level control
Control directions – For emptying of tank
Level control mode – Controlled by 4-20mA hydrostatic level transducer and/or low, duty stop, duty start, standby starts and high level float switches, submerged in a tank or pit
Maintain minimum level – Ensures minimum tank level is maintained in (specific to level mode, empty direction)
Sleep modes – Sleep can be enabled to allow pumps to sleep when setpoint is reached, or disabled so one pump is always running to circulate water
Fault Protection
Protection modes – Apply to most protections, and include alarm (alarm only), lockout (alarm and pump shutdown) and inhibit (pump shutdown only, no alarm)
High and low level, pressure or temperature protection – Alarm and/or shutdown on high and low level, pressure or temperature depending on the system type, low pressure protection features automatic restart attempts
Auxiliary tank level protection – Pump shut-down on supply tank low or destination tank full
Pump anti-seize protection – Runs pumps periodically during low use to prevent seizing
Maximum run protection – Activates after pumps run at max speed for 30 mins, protecting the system in the event of a burst pipe, with automatic restart attempts
Pump cycle protection – Activates if system goes to sleep but wakes up within 5 seconds, 10 times in a row, due to a faulty non-return valve or similar fault preventing the system from maintaining pressure
Feedback signal fault protection – Shuts down all pumps in the event of a transducer failing
Pump overload protection – Shuts down pump/s on overload, with automatic duty alternation
Pump thermal switch protection – For three phase pumps
