SPYDER® BACNET® PROGRAMMABLE CONTROLLERS
63-2689—05 12
Table 7. Description of wiring terminal connections for
PUB6438S, PVB6436AS, and PVB6438NS.
IMPORTANT
If the controller is not connected to a good earth
ground, the controller's internal transient protection
circuitry is compromised and the function of protect-
ing the controller from noise and power line spikes
cannot be fulfilled. This could result in a damaged cir-
cuit board and require replacement of the controller.
Refer to installation diagrams for specific wiring.
All controllers have the terminal arrangements similar to the
examples shown in Fig. 15 as described in Table Table 7 on
page 12.
MS/TP MAC ADDRESS DIP SWITCHES
The MS/TP MAC address DIP switches are used to set the
unit's MAC address. Each Spyder BACnet on an MS/TP
network must have a unique MAC address in the range of 0-
127 (address 0 should be avoided as it is the Honeywell factory
default MAC address for all MS/TP devices).
MS/TP SERVICE CONNECTOR PINS
Local device MS/TP network connection is provided via the
molex connector pins (0.100-in. molex connector—part
number: 22-01-2035).

address DIP switches, MS/TP service connector pins, and
BACnet Status LED for the PUB's and PVB's (PVB6438NS
shown).
Wiring Applications (Examples)
Fig. 16–Fig. 22, beginning on page 13, illustrate controller
wiring for the following configurations.
• Typical controller wiring for VAV application using the TR23
Wall Module and a C7770A Air Temperature Sensor (see
Fig. 16 on page 13).
• Typical controller wiring for VAV application with staged
reheat (see Fig. 17 on page 14).
• Typical controller wiring for PWM reheat and PWM
peripheral heat valve actuator (see Fig. 18 on page 15).
• Typical controller wiring for AHU application (see Fig. 19 on
page 16).
• Typical controller wiring for 4 to 20 mA enthalpy sensors and
digital inputs (see Fig. 20 on page 17).

a
For the PVB6436AS controller ONLY, terminals 18, 19, and 20 (DO7,
DO8, & COM) are not present. The actuator is internally hardwired to
these terminals.
b
Analog outputs may be configured as digital outputs and operate as fol-
lows:
– False (0%) produces 0 Vdc, (0 mA)
– True (100%) produces the maximum 11 Vdc (22 mA)
c
Digital inputs: Open circuit = False; Closed circuit = True
