Page 3: General Information
General Information The name “Varivac” is a protected Trademark belonging to Corkill Systems Limited, unauthorised use of this name will lead to prosecution. Varivac is available in standard motor sizes from 4 kilowatts to 30 kilowatts, model CSLV4B has a 4 kilowatt capacity, CSLV5B is 5.5 kilowatt, etc. A kit is available called the tandem kit witch will convert the VARIVAC into a Tandem pump controller, this model controls two motors simultaneously and has individual motor circuit- breakers to protect the motors. - Page 4 The cable between the Varivac and Transducer is to be of minimum 0.2mm 2 core screened twisted pair and not to be run parallel with heavy current carrying cables. Belden type cable is preferred and we normally supply this with the Varivac. Earth the screen at both ends and keep the tails as short as possible.

Page 5: Mounting And Wiring
Mounting and Wiring Single Pump & Motor Combination This system consists of one motor with one or more vacuum pumps attached. 1. Generally mount the Varivac adjacent the vacuum pump. The main factor in choosing the Varivac location is keeping the EMC cable to the motor as short as possible. 2. - Page 6 Tandem Pump & Motor Combination This system consist generally of two motors wired separately each with one or more vacuum pumps attached. These motors may be of different sizes, this does not matter! 1. Generally mount the Varivac close to the vacuum pumps. The main factor in choosing the Varivac location is keeping the EMC cables to the motors as short as possible.

Page 7: Transducer Installation
Transducer Installation General; mount the transducer as close to the cows as practical and possible, the sensing face is VERY sensitive and easily damaged, be very careful with it. Only mount the transducer in the Vacuum Interceptor when no other option is practical – it will still work well but in high vacuum loss situations the vacuum at the cups will be lower than at the transducer sensing face due to friction losses in the plant pipe work. - Page 8 Rotary Dairy – mount as close as possible to the gland. Using a tee as in the installation photos below moves the transducer out of direct air flow – this is good. There is often a spare outlet in the gland, which is a good point to mount the transducer – beware of the transducer being accidentally knocked by operators or moving pipe work.

Page 12: Auxiliary Equipment Setup
Auxiliary Equipment Setup Switching auxiliary equipment via the Varivac For remote switching of auxiliary equipment use the sacrificial Relay contacts on DIN rail terminals #12 and #13. This is a programmable clean set of contacts to operate pulsators cooler pumps etc... Warning - this relay will switch up to 400 volts do not load to more than 5 amps !! Using the Danfoss relay #2 directly is not recommended. -
Page 13: Vacuum Level Adjustment
Vacuum Level Adjustment Setting the air regulator(s) There are two basic types of air regulators; remote sensing and the standard type. Remote sensing types have a long pipe attached to the air regulator and to a sensor. The sensor is mounted on the main vacuum line above the pit in herringbone sheds or close to the gland in rotary sheds. -
Page 14: Trouble Shooting
The factory maximum speed setting is 55 Hz. This can be adjusted by opening clusters until the top speed is reached (this can be seen on the screen, press the “Status” button if required). The speed can be raised or lowered by changing Parameter #414. Set the maximum speed so that the kilowatt reading is approximately 15% above the nameplate rating. -
Page 15: Common Error Messages
Drive won’t speed up in variable speed modes Cause: Internal reference set points are set incorrectly. Break in transducer cabling or transducer wired incorrectly into Varivac. Remedy: Check to see if Varivac is working by temporarily shorting terminals #1 and #2. Drive should speed up indicating that there is a fault with the reference adjustment or transducer. - Page 16 Cause: The electronic, thermal inverter protection reports that the frequency converter is about to trip because of an overload (current too high for too long). The counter for the electronic, thermal inverter protection gives a warning at 98% and trips and enters alarm state at 100%.
