Parameter Descriptions

Number

Parameter

Description

P-01

Transducer Span

Range of the transducer

P-02

Transducer Offset

Transducer value below zero

P-03

Target

Pressure target, control will try to maintain this pressure

P-04

Target Above P-03

Set-point above the target, used to obtain a “dead-band”

P-05

Target Below P-03

Set-point above the target, used to obtain a “dead-band”

P-06

Stages

Number of stages in the system

P-07

Stage On Delay

Delay time between stages on

P-08

Stage Off Delay

Delay time between stages off

P-09

Fail Off / On

The following will occur in the event of pressure transducer fault.

If set to On then all Compressors or Fans will turn On in the event of a transducer failure. If set to Off then

all Compressors or Fans will turn Off in the event of a transducer failure.

P-10

Service Time

Time controller is running (in 1000 x hours) before the service icon (Spanner icon) comes on. Reset the

spanner icon to off by changing this parameter to 0 and then back to the desired service interval.

P-11

Run Proof

See section : Run Proof

P-12

Optimisation Limit

This is an offset that is added to the target pressure when using the Data Manager Energy feature Pack

Optimisation. For example if target pressure is 2.1 Bar and Optimise Limit set to 0.5 Bar. The remote

optimise command will only be able to optimise the current suction setpoint up to a maximum of 2.6 Bar

P-15

Control Type

Selects between Fixed or Floating. For Condenser control only.

Fixed uses the set-point parameter as its target (P-03)

Floating uses the temperature of a selected probe converted to a pressure as the set-point

P-16

Probe Select

Selects the probe that measures the “floating” temperature

(Note : This would be fitted to the Air On of the Condenser)

See note : Floating Head Pressure

P-17

Low Limit

Stops the floating pressure target from going below this level

P-18

High Limit

Stops the floating pressure target from going above this level

P-19

Condenser Offset

Allows for an offset to be added to the ambient temperature probe used in the “floating” set-point feature.

P-20

Alarm Delay

Delay before HP and LP alarms are signalled

P-21

HP Alarm

HP alarm set-point

P-22

LP Alarm

LP alarm set-point, stage off when reached

P-23

LP Shutdown

Point at which LP Shutdown alarm is generated. Note as soon as the LP Shutdown setpoint is reached

any Compressor/Condenser stages, for the associated section, still operating will go off immediately and

does not wait for the LP Shutdown alarm to be created.

P-30

P-34

Status Fault 1

Status Fault 5

Used to select the type of input required

P-40

Status Fault Delay

Time delay before status faults are activated

P-41

General Fault Delay

Time delay before general faults are activated

P-44
