Alarms; Control Parameters - Danfoss Optyma Plus User Manual

Max. condensing temperature (highest permitted Tc reference)
Max. discharge gas temperature Td

Alarms

Alarm time delay on signal on the DI2 input
Alarm for insufficient cooling in condenser. Set temperature difference.
Delay time for A70 alarm
Compressor
Min. ON-time
Min. OFF-time
Min. time between compressor starts
Pump down limit at which the compressor is stopped (setting 0.0 = no function)
Min. compressor speed
Start speed for compressor
Max. compressor speed
Max. compressor speed during night operation (%-value of c48)
Definition of compressor control: 0=no external start/stop; 1=switch on DI1 must start/stop
; 2=inverter compressor speed control
Time delay for high Td. The compressor will stop when time expires.
Max. pressure. Compressor stops if a higher pressure is recorded
Difference for max. pressure (c73)
Min. suction pressure Ps. Compressor stops if a lower pressure is recorded
Difference for min. suction pressure and pump down
Amplification factor Kp for compressors PI-regulation
Integration time Tn for compressors PI-regulation
Liquid Injection Offset
Liquid Injection hysterese
Compressor stop delay after Liquid injection
Desired compressor speed if the signal from the pressure transmitter Ps fails
Min On time during Low Ambient LP
Measured Tc for which the Comp min speed is raised to StartSpeed

Control parameters

Amplification factor Kp for PI-regulation
Integration time Tn for PI-regulation
Kp max for PI regulation when the measurement is far from reference
Fan
Readout of fan speed in %
Permitted change in fan speed (to a lower value) % per second.
Jog speed (speed as a % when the fan is started)
Jog speed at low temperature
Definition of fan control: 0=Off; 1=Internal control. 2=External speed control
Minimum fan speed. Decreased need will stop the fan.
Maximum fan speed
Manual control of the fan's speed. (Only when r12 is set to -1)
