The following table (table 4.2) shows the specific function codes for multi-regulated pump control system
with 2/3 regulated pumps:
Table 4.2: Specific parameters for Multi-regulated pump control with 2/3 regulated pumps
Note:
The default setting for function code J94 (0 Hz) may work properly in your installation without
adjusting it to the suggested value (39 Hz).
DESCRIPTION OF SPECIFIC PARAMETERS OF MULTI-REGULATED PUMP CONTROL WITH
2/3 REGULATED PUMPS
PID and pump control
J25: Pump control. Mode selection
The function code J25 defines which type of pump control is going to be used
J25 = 0 Pump control disabled
J25 = 1 Mono-regulated pump control enabled
J25 = 2 Multi-regulated control enabled
J26, J27, J28: Motor 1 mode, Motor 2 mode, Motor 3 mode
The function codes J26, J27, J28 define:
J26 = 0 pump 1 unavailable
J26 = 1 pump 1 available
J26 = 2 pump 1 connected to the commercial power supply
J27= 0 pump 2 unavailable
J27 = 1 pump 2 available
J27 = 2 pump 2 connected to the commercial power supply
J28 = 0 pump 3 unavailable
J28 = 1 pump 3 available
J28 = 2 pump 3 connected to the commercial power supply
In normal operation, the mode to be used is 1.
