Field Relay 7 and 8 –
This shows the state of the Field Relay 7
and 8 on AXB A and B (labeled K6). When Field Relay is “ON”
the Field Relay 1 and 2 will be engaged. The output is wired
directly to top of relay on AXB A and B K6
ACC2 (A and B) -
This shows the state of the ACC 2 relay on
the two AXB’s. When ACC 2 is “ON” the ACC 2 relay will be
engaged.
Other User Defined Field I/O
Field Temp 1 and 2 -
Can display the temperature of a fi eld
supplied 10k Ohm NTC thermistor connected to AXB A or B
P1-LVG Air.
Field Temp 3 -
Can display the temperature of a fi eld supplied
10k Ohm NTC thermistor connected to AXB A P17-HWT.
Field Press 1 and 2 -
Can display the pressure of a fi eld
supplied pressure transducer connected to AXB A P3-Loop
Pres. Consult technical support for more details.
Both Circuit A and Circuit B are shown on screen.
Field DI 1 and 2 -
Can display the logic (Off/On) of the Field DI
1 and 2 input on the AXB A and B pin P4 – Smart Grid. Consult
technical support for application details.
Flow Switch Inputs (HA1-Source, HA2-Load) -
All fl ow switch
inputs will be checked 5 seconds prior to either compressor
starting. If the fl ow switches are not closed the compressor(s)
will not start. While the compressor(s) is operating if either
fl ow switch opens for 5 continuous seconds the compressor(s)
will be immediately shut down until fl ow returns. If fl ow does
not return within 60 seconds the controller will issue an E-31
fault code for Source Flow or an E-32 fault code for Load
Flow. If at any time the fl ow returns for 15 continuous seconds
the fl ow fault will automatically reset and the controls will be
allowed to resume normal operation
.
Field Amps 1 and 2 -
Can display the current draw using a fi eld
installed current transducer on the AXB A and B pin P10 – Fan.
Consult technical support for application details.
Field AO 1 and 2 -
Can display the output (0-10V) of the
optional fi eld installed analog output device. Outputs are
connect to AXB A and B P11-ANA. Consult technical support
for application details.
Field Relay 1 and 2 –
This shows the state of the Field Relay 1
and 2 on AXB A and B (labeled DH). When Field Relay is “ON”
the Field Relay 1 and 2 will be engaged. The output is wired to
AXB A and B P11 – DH.
Field Relay 3 and 4 –
This shows the state of the Field Relay
3 and 4 on AXB A and B (labeled DIV). When Field Relay is
“ON” the Field Relay 1 and 2 will be engaged. The output is
wired to AXB A and B P11 – DIV.
Field Relay 5 and 6 –
This shows the state of the Field Relay 5
and 6 on AXB A and B (labeled K5). When Field Relay is “ON”
the Field Relay 1 and 2 will be engaged. The output is wired
directly to top of relay on AXB A and B K5
