Pump standstill
The wave packet method (standard) allows for variations in the volume flow by a factor of
10 in 30 increments. If the flow rate is too low, flap valves may cause a system standstill. In
addition, low power stages at low speeds may cause the rotors to stop. Such a standstill may
sometimes be desired, which is why stage 0 is allowed as the lowest stage. The following
parameters determine the lower and upper limit for speeds:
MIN Lower speed limit (ex works = 0)
MAX Upper speed limit (ex works = 30)
The best speed limit is found in a simple test. Use the command TST to set a speed for
testing. Remove the rotor lid to see the rotor. Then lower the speed until the rotor stops. Set
the limit three increments above this point to ensure safe pumping.
Control commands
The following commands provide a test of the system (see pump standstill) and allow you
to monitor the current speed (see stability problems):
ACT 19 The pump is currently running at stage 19 (actual value).
TST 14 The speed stage 14 is currently being tested. Calling TST automatically switches
to manual mode. As soon as the value blinks via the key � (= entry), the pump
runs at the speed displayed.
Setting range: 0 to 30
