6.4.4 Connections and Setup of ADR 80 and 230 with 1 or 2 Sensors
ADR 80 / 230 with 1 Sensor
•
For one circuit
•
Single or three phase motors
•
By use of pressure transmitter after setting to a refrigerant
Control and Display in bar or °C.
•
With temperature sensors Setup and Display in °C
ADR 80 / 230 with two Sensors
•
For two circuits
•
Single or three phase motors
•
By use of pressure transmitter after setting to a refrigerant
Control and Display in bar or °C.
•
With temperature sensors Setup and Display in °C
•
Control with 1 Set point
Setting in
2 Sensors
“SETUP”:
1 Set point
Both refrigeration circuits are controlled
by the highest pressure or temperature of circuit 1 or 2
Bypass (SET 1)remains open.
•
Control with 2 Set points
Setting in
2 Sensors
“SETUP”:
2 Set point
Signals of circuit 1 and 2 will be used in accordance if Bypass
is open or closed. Bypass can be opened or closed by timer,
switch, Thermostat
or any other device (potential free).
Bypass open (SET 1): Circuit 1 takes over control
Bypass closed (SET2): Circuit 2 takes over control
Attention
: By using one or two pressure transducer the con-
trol has to be set to Pressure despite that setup and display is
set to temperature °C
Setup in Temperature will be made when one or two NTC
Sensors are connected to ADR
By using pressure transducer with 0-10 volts output
in
mode
“SETUP”
“PRESSURE”
Probe-Type
0-10V
has to be chosen.
Setup for REGULATION in mode “VOLTAGE” has to be
chosen for external controls 0 – 10 Volts.
In that case ADR is acting as slave according to the
commands of an external SPS Control.
