Using the RS485 output to communicate
with BACnet
You can optionally connect the A525 Fermentation
Controller to a supervisory controller through a BACnet
MS/TP bus for remote monitoring and programmability
within a building automation system (BAS).
The A525 Fermentation Controller uses the isolated
RS485 output on the BACnet expansion interface to
communicate with BACnet. See the following figure for
an example of the BACnet expansion interface on the
controller.
Figure 6: BACnet expansion interface on the A525
Fermentation Controller
Connect the network terminal block on the A525
Fermentation Controller to the other devices in a daisy-
chain configuration using three-wire twisted, shielded
cable.
The isolated cable shield drain (SHD) terminal on the
network terminal block splices the cable shields along the
daisy-chain. See the following figure for more information
about daisy-chain configurations.

Adding the A525 Fermentation Controller to a
daisy-chain configuration for communication
with BACnet
To add the controller to a daisy-chain configuration for
communication with BACnet, complete the following
steps:
1. Connect the network terminal block on the A525
Fermentation Controller to the other devices in the
daisy-chain configuration using three-wire twisted,
shielded cable.
2. Determine the physical location of the controller
connection on the daisy-chain network trunk.
3. If the controller is a terminating device on the
network trunk, push the EOL switch upwards to set it
to on. If the controller is not a terminating device on
the network trunk, push the EOL switch downwards
to set it to off.
4. Configure the BACnet address in the A525
Fermentation Controller’s UI. Refer to the A525
Electronic Fermentation Tank Controller Technical
Bulletin (LIT-12013007) for more information.
Note:
- Make sure that the network cable SHDs
are spliced at all of the subordinate
devices on the trunk.
- Make sure that the cable shield connects
to the ground at the master device only.
- The EOL switch on the A525
Fermentation Controller is set to off by
factory default.

Sensor wiring
See Table 7 for information about wire gauge and
maximum sensor wire length. See Table 16 for
information about the temperature sensor’s technical
specifications.
Observe the following guidelines when you wire sensors
to the A525 Fermentation Controller:
• Sensor leads are not color coded or polarity-specific;
you can connect either of the two sensor leads to the
Sn1 terminal and a C terminal.
• Select only the sensor that operates in the ambient
operating range that your A525 Fermentation
Controller monitors and controls.
• Keep the sensor leads as short as possible in your
application. The additional resistance in long sensor
cables can create an offset between the actual
temperature and the displayed temperature. It is best
practice to solder or butt splice connections.
• Use 0.30 mm2 (22 AWG) stranded-wires and twisted-
leads cable with a cable shield to extend sensor cable
runs.
Table 7: Maximum recommended sensor cable lengths
and wire sizes
Wire gauge Maximum sensor cable length 1
1.3 mm2 (16 AWG) 150 m (492 ft)
0.82 mm2 (18 AWG) 100 m (328 ft)
0.52 mm2 (20 AWG) 60 m (196 ft)
0.33 mm2 (22 AWG) 40 m (131 ft)
1 At the listed cable lengths, there is less than 0.6°C (1°F) error
between the temperature sensed at the TE-631AP-1 sensor
and the temperature displayed on the LCD.1
Important: When you connect sensors with
shielded cable to a control, connect the cable shield
drain lead to one of the C terminals on the input
sensor terminal block. Do not connect the shield at
any other point along the cable. Isolate and insulate
the shield drain at the sensor end of the cable.
Connecting a cable shield at more than one point
can enable transient currents to flow through the
sensor cable shield, which can cause erratic control
operation.
