Page 5: Device Setting
When demand decreases -or as the current pressure value surpasses the set value- the pump with the driver slows down and attempts to match the reference pressure value. The pumps are deactivated if they are no longer needed. www.etna.com.tr... - Page 6 If in circulation mode, the EPLC-6 control unit first calculates the difference between two sets of data collected from the 4-20 mA pressure transmitters (transmitter1-transmitter2, where transmitter1 is the value gathered from the transmitter at the entrance of the fixture and transmitter2 is from the transmitter at the exit of the fixture) and then compares this to the set differential pressure value at which the device is desired to work.

In booster pump mode, wakeup pressure is the differential pressure value at which the wakeup (pump activation) period starts counting, which is identified to prevent the system from continuously activating and deactivating and which can be adjusted as needed. www.etna.com.tr... - Page 8 p : Wake-up pressure t1 : Pump start delay time t2 : Pump stop delay time P (bar) Wake up zone Set Pressure Wake-up pressure t (sn) Pump on demand t (sn) Graph 1: Pump ON / OFF vs. Wake-up Pressure on Constant Pressure Mode For example, if the set pressure is 8 bars and wakeup pressure is 0.5 bars, a standby pump will activate after the current system pressure drops below 7.5 bars and the wakeup period is complete.

Set Pressure: Set pressure is the pressure value at which the system is expected to work. In booster pump mode, it is associated with the value read off of pressure transmitters. In circulation mode, it is associated with the difference between the values read off of transmitter1 and transmitter2. -

3 levels; In the 1st level, the reaction speed on the 1st level is slow and as the level is increased, the rotation speed in the reference speed relayed by EPLC-6 panel to the driver also increases. Therefore, the pump rotation speed that works with the driver also varies in proportion to the reaction speed. www.etna.com.tr... - Page 12 Sleeping Period: Sleeping period is the condition when, in booster pump mode, the system's current pressure is higher than the set pressure and when pumps stand by ready to work, without working. In systems with drivers, if the system pressure is above the set value and if the driver frequency is lower than the deactivation frequency value and remains that way throughout the sleeping period, the system enters sleep mode.
