Pump Protection Relay
MODEL A-PPR - 1T8 - 23 PRODUCT Pump Protection Relay with phase Failure Protection and Underload Restart Timer Function - 230V DESCRIPTION OF OPERATION The PPR is designed for use on motors which require sensitive overload and underload protection and is particularly suitable for offering good protection on borehole and pump set motors. The PPR offers phase failure protection which is voltage or current dependent. On power up all 3 phases must be present and connected in the following manner. L1 is used for the PPR ON/ OFF control energising the unit on terminal 2. L2 connects to terminal 8. L3 connects to terminal 10. On single phase units, terminal 10 is connected to Neutral. During running the phase failure protection is dependent on the current transformer and if the PPR is set correctly, it will respond extremely fast. Both overload and underload have Set/Trip point LEDs with a common adjustable 0-10 second trip delay timer. There is fixed start-up delay of 5 seconds. A 50/5 CT, with a option of 3 connections (turns through CT), and 1 & 5 amp DIP switch selection provides various settings for motors 0.37kW to 7.5kW. For larger motors any size ring CT with a 5 amp secondary can b be used. The PPR is fitted with a underload re-start timer controlled by 4 DIP switches offering 6 time settings from 20 minutes to 8 hours (for borehole recovery). If the installation is fitted with a discharge valve and ammeter, the over and under setting combinations are numerous with loads very easy to simulate. VOLTAGE 230V AC

3 Level Liquid Level Relay
MODEL A - LLC3 PRODUCT 3 Level liquid Level Control “Filling & Emptying” with duty cycling DIP Switch Selectable DESCRIPTION OF OPERATION Used for control of water levels in tanks and sumps over short distances. The LLC3 controls 2 pump relays operated at different levels for “Duty” and “Standby” operation. The unit automatically alternates the pump relays between duty and standby using a built-in flip- flop action. There are 4 DIP switches available to select emptying or fillingFilling: Sw 1 + 2 - ON (up position); Sw 3 + 4 - OFF (down position) Emptying: Sw 1 + 2 - OFF(down position); Sw 3 + 4 - ON (up position) Avanti AEL probes: connected to the terminals:5 - “High;” 6 - “Middle;” 7 - “Low;” 8 - “Common” Filling: If the level is below probe 7 - “Low” both relays will energise and when the level reaches probe 5 - “High” both relays will de-energise. When the level drops below probe 6 - “Middle” relay 1 will energise and de-energise when the level reaches probe 5 - “High.” The next on cycle with probe 6 - “Middle” out of the water, relay 2 will energise (alternating). If the level continues to fall and goes below the probe 7 - “Low,” both pumps will energise and only de-energise when probe 5 - “High” is reached (all probes in the water). Emptying: When a rising level reaches probe 6 - “Middle,” relay 2 energises and de-energises when probe 7 - “Low” is reached. On the next rising level to probe 6 - “Middle” - relay 1 will energise (alternating). If the level continues to rise and probe 5 - “High” is reached, both relays will be energised (Duty & Standby) and when the level reaches probe 7 - “Low” both relays will de-energise.

2 Pump Distance Control Unit
MODEL A-DCU / 2 PRODUCT 2 Pump Distance Control Unit DESCRIPTION OF OPERATION To control water levels in sumps, dams, tanks, etc. Operation is the same as the normal DCU but this unit can control 2 pumps operating at different levels. 3 Float switch (24V DC) - 4 Wire control: Stop float - normally closed contact connected to terminals 6 + 7. First start float - normally open connected to terminals 5 + 6. Second start float - normally open connected to terminals 4 + 6. Closing 5 + 6 (1st start float) will energise relay No. 1 and closing 4 + 6 (2nd start float) will energise relay No.2. Both start relays will remain energised until the stop float opens between terminals 6 + 7. This system is used for “Duty Pump” and “Stand- by Pump” applications. Where only one pump with an alarm is required, relay No.1 is used for the pump and relay No. 2 for the alarm. Where 2 pumps and alarm are required, a normal DCU can be used for the alarm operation. If this system is used, a seperate float must be used dedicated to this DCU. The interconnection of the two 24 Volt float outputs of the DCU/2 and DCU must be avoided at all times.
