7.6.2 Fixed MASTER This is the default setting of the Pump Control. The AC drive controls the Master pump which is always running. The relay outputs start and stop the other pumps P1 to P6, depending on flow/pressure. In this configuration a maximum of 7 pumps can be controlled, see Fig. 43. To equalize the lifetime of the additional pumps it is possible to select the pumps depending on the run time history of each pump.

After the AC drive is powered up or started again after a stop or sleep mode the Master pump is selected via the relay set to function Master Pump. section 7.6.7 on page 44 shows a detailed wiring diagram with 3 pumps. The purpose of this function is that all pumps are used equally, so the lifetime of all pumps, including the Master pump, will be equalized. Maximum 6 pumps can be controlled with this function.

7.6.4 Feedback 'Status' input In this example the additional pumps are controlled by an other kind of drive (e.g. soft starter, frequency inverter, etc.). The digital inputs on the I/O Board can be programmed as a "Error" input for each pump. If a drive fails the digital input will monitor this and the PUMP CONTROL option will not use that particular drive anymore and automatically FDU MASTER feedback inputs (NG_50-PC-6_1) Fig. 50 Feedback "Status" input PM 7.6.5 Fail safe operation Some pump systems must always have a minimum flow or pressure level, even if the frequency inverter is tripped or damaged. So at least 1 or 2 (or maybe all) additional pumps must keep running after the inverter is powered down or tripped. This kind of "safe" pump operation can be FDU MASTER (50-PC-7_1) R:SlavePump3 R:SlavePump2 R:SlavePump1 DI:Pump1Feedb DI:Pump2Feedb DI:Pump3Feedb R:SlavePump6 R:SlavePump5 R:SlavePump4 R:SlavePump3 R:SlavePump2 R:SlavePump1 PM Fig. 51 Example of "Fail safe" operation other drive other drive P1 P2 P3 switch to another drive. This means that the control continues without using this (faulty) drive. This function can also be used to <strong>manual</strong>ly stop a particular pump for maintenance purposes, without shutting down the whole pump system. Of course the maximum flow/pressure is then limited to the maximum pump power of the remaining pumps. obtained by using the NC contacts of the pump control relays. These can be programmed for each individual additional pump. In this example pumps P5 and P6 will run at maximum power if the inverter fails or is powered down.
