Function Block PUMP_ANTIJAM
| Available as of PLC runtime system | V1.3 and above |
| Included in library | PUMP_AC500_V23.lib |
| Type | Function Block without historical values. |
Note
Performs the pump Antijam/cleaning functionality by running the pump at high speeds without any ramp up/down time. For the cleaning function to be performed properly it is important to disable the drive ramp function generator. This can be done if the programmer latches the DRIVE_RFG_DISABLE output with the corresponding bit in the drive control word.
Pump cleaning function can be used to prevent solids from building up on pump impellers or piping. The function consists of a programmable sequence of forward and reverse runs of the pump to shake off any residue on the impeller or piping. This is especially useful with booster and wastewater pumps.
The cleaning sequence can be programmed to occur at suitable intervals, or whenever certain triggering conditions are met.
Note
Not all pumps can be rotated in the reverse direction.
