GENERAL The units are designed to work independently, or in conjunction with other equipment via ISN, Bacnet or Modbus building management systems or other automated control systems. When operating, the unit controls monitor the chilled liquid system temperatures at the unit and take the appropriate…

Load Limiting Load Limiting prevents the unit from loading beyond a desired value. 4 compressor units can be load limited to 50% of the compressors by allowing only 1 compressor per system to run. 5 compressor units can be load limited to 40% or 80% of the compressors. The 80% would allows a up 2…

Operation The operating sequence described below relates to operation on a cooling demand start after power has been applied, such as start-up commissioning. When power is applied to the unit a 2 minute timer will start. This timer also prevents instantaneous starting after a power failure if the…

The lag compressors in a system, are not controlled by

the anti-recycle timer. They have no start to start timer other than the effect of system lead/lag rotation and the load/unload timers. For a given compressor this gives a minimum start to start time of 140 seconds on systems with 2 compressors or 210 seconds on systems with 3 compressors. Their…

To ensure reliable operation of the unit the software will modify the operation of the 'Leaving Chilled Liquid Control' as follows: Each compressor is fitted with a crankcase heater (not controlled by the micro processor) which is ON when the compressor is OFF. 1. If the run time of the lead system…

Lead/Lag Control The chiller may be set up for AUTO or MANUAL lead/lag. This is accomplished by programming the option under the 'OPTIONS' key. When AUTO lead/lag is used, the microprocessor attempts to balance run time between the systems. A number of conditions can occur which will prevent this…

YLAA and YLAE 2 Speed Fan Option The reason for two speed fans it to reduce unit noise by running the fans in slow speed over as wide a range of conditions as possible, only going to full speed as a last resort. This is achieved by raising the pressure at which the last fan stage occurs, switching…

Pressing the 'PRINT' key and then the 'HISTORY' key allows the operator to obtain a printout of information relating to the last 6 Safety Shutdowns which occurred. The information is stored at the instant of the fault, regardless of whether the fault caused a lockout to occur. The information is…

ENTRY KEYS The Entry Keys allow the programmed values to be viewed and changed. 6.1 7 Programming and viewing the cooling setpoints, daily schedule, and safeties is accomplished by using the 'SETPOINTS' keys: UP ARROW and DOWN ARROW Keys 7.1 Used in conjunction with the 'OPER DATA' and 'HISTORY'…

The ‘RANGE’ setting takes into account the number of

compressors on the unit and the temperature difference between leaving (LCHLT) and return chilled liquid at full load. The 'RANGE' is programmed for +/- X.X° C. The 'SETPOINT' is in the centre of the control range. For further details of cooling setpoint programming refer to Capacity Control.…
