Functional Control for a Standalone Unit ESIE05-07

2–70 Part 2 – Functional Description

Possible settings (Service menu):

P Simulation setting:

P AI Setting:

P AO Setting:

P DIS. EEV Setting:

P STL Setting:

Simulation parameter Application

Simulation = NO actual unit

Simulation = YES simulation board is selected

Simulation parameter Application

AI = 0 actual unit = actual sensors are used on

the analog inputs

AI = 1 simulation board (all analog inputs use

potentiometers = NTC)

Simulation parameter Application

AO = 0 variable analog output from 0V to 10V

AO = 1 analog output with 2 possible outputs,

0V or 5V output

Simulation parameter Application

DIS. EEV = 0 actual unit with EEV driver

DIS. EEV = 1 If no EEV driver is connected to the

simulation board this parameter should

be put on 1. This will dissable the EEV

control on the controller.

Simulation parameter Application

STL = O actual unit, controller uses the feedback

from the compressor. The compressor

capacity is calculated based on the

feedback value

STL = 1 if no compressor control motor is con-

nected to the controller of the simulation

board, then this parameter should be

programmed on 1. Now the controller

will simulate the feedback resistance.
