P10- Ventilator switch on temperature threshold
• Defines the oil temperature threshold, exceed that, it is activated a command output for a ventilator
• In normal conditions, this parameter needs no adjustment.
P11 – Ventilator switch on temperature hysteresis
• Defines the hysteresis range to control the command output for a ventilator
For example, with P10=70°C and P11=5°C, the command output for the ventilator is activated when the oil
temperature is above 70°C and it is deactivated when the temperature is below 65°C.
P12 - Star time
• Defines how long the system should run in star configuration during motor start-up.
• In normal conditions, this parameters needs no adjustment.
P13 - Star-delta switching time
• Defines the delay between the release of the star contactor and the coming into operation of the delta
contactor, during the switching stage.
• In normal conditions, this parameter needs no adjustment.
P14 - Launch time
• Defines the delay between the coming into operation of the delta contactor and the energizing of the
load/unload solenoid valve; such delay is added to permit the motor to reach its rotation speed
subsequent to the star-delta switching.
• In normal conditions, this parameter needs no adjustment.
P15 - Unload time
• Defines the duration of the unload operation interval, at the end of which the controller will power off the
motor.
• Unload operation is identified by a flashing LED ( / ).
• If this value is set at 0s, the compressors switches off when it enters in the unload phase. The compressor
starts again when the load condition occurs but not before that a restarting delay is elapsed ( parameter
P17- default 15 s).
P16 – Delay time for switch off
• Defines the necessary time to switch off the compressor after pushing the OFF button or opening the
START/STOP remote contact.
• The signalling for the compressor switch off is shown on the display from the OFF and LEDx10 flashing.
P17 – Delay time for restaring
• Defines the inhibition time from restarting after the compressor has been powerd off. Its purpose is to
prevent any restarts of the compressor while pressure is still in the tank
• The restarting inhibition condition is identified by a flashin x10 LED. The motor restarting is inhibited for the
set time interval
