PEERLESS 10HP Variable Speed Rotary Screw Compressor

• Adjust Pressure to the range you need. In addition, this unit has an automatic shutdown, in the event it goes over pressure. Because the unit has a maximum pressure setting, the PLC will sense that it is going over pressure and will shut down.
• Low Oil Shutdown – if the controller senses that the unit is going into high temperature, it will shut it down. It will also shut down if the compressor runs low on oil.
• Reverse Fault – the controller will determine, when the unit is wired up, if it is in reverse rotation fault and shut the unit down.
• High Voltage Fault – if the voltage is 15% over the power supply voltage, rated on the Polar compressor data plate, the unit will shut down. As well, if the voltage is 15% under what it should be, the unit will shut down.
• Over AMP Shut down – if the motor is pulling too many amps, it will shut down. You can check the amp draw of the electric motor, as it is running, and also on the exhaust fan motor
• Clock and Date – built in Clock and Date to help keep track of preventative maintenance services.
• Light – has a built in light for dark locations.
• Parameters – has a maintenance parameter system to create and maintain the parameter and control information.
• Hour Meter – built in hour meter to keep track of the running hour on the machine.
• Fault History – the PLC stores history, if the unit shuts down, and can provide information on why the unit shut down.
• Maintenance Service – keeps track of when to change the air filter, oil filter and the coalescing filter, along with a schedule of when the unit needs greased. When any of these issues need addressed, the PLC will sound an alarm. After addressing the maintenance issue, you simply reset that element back to zero and start the maintenance tracker again.
• Air Differential Control – with differential control, you have a wide range of pressure settings. You can take the kick-in pressure all the way down to 100 PSI and all the way up to 145 PSI. You can also adjust this range anywhere in between. The Polar Compressor is factory-set at 120 kick in and 145 kick out. The lower the pressure, the higher CFM and the more hours you will get on your rotary screw air compressor, so keep the pressure as low as possible.
• Built in Timer – this component will sense when the unit is not being used for a period of 20 minutes, under no load. This will shut down the machine, automatically, and it will restart, as air pressure goes down, to the kick-in set point.
• Online Demand – this setting is made for high volume and will bypass the automatic kick-off mode. It allows the unit to keep running on continuous run mode for high air demand.
• Warranty – these PLCs carry a 5 year warranty.
• Daily / Weekly Schedule – this unit can be programmed to start in the morning, can shuts itself off at lunch, if needed, and can turn itself on based upon a pre-programmed schedule.
• Self Start – if power is lost, this unit will automatically restart itself, this eliminates a maintenance crew to have to restart it, after the shut down.
• Master Slave – this controller can switch from one unit to the other and maintain the same use of hours. It can also adjust the pressure to be the lead or the lag unit.
