SETTING TIME AND DATE — The date and time for the
controls can be set by opening the Main Menu Configuration
Menu Date/Time Configuration. The date, time, day of the
week, and daylight saving time option can be set on this screen.
WEB AND NETWORK INTERFACE — The Touch Pilot
control can be configured to allow access via a standard, java-
enabled web browser or over a network. See Appendix H for
detailed information on setting up and accessing the Touch Pi-
lot via the web or network interface. See Table 5 for port con-
nections. See Fig. 15 for interface and connectors.
Table 5 — Touch Pilot Display Port Connections
Input/Output (SIOB) Boards — There are two
SIOB (Standard Input/Output Boards) boards for each unit,
SIOB-A (address 49) for Circuit A and SIOB-B (address
50) for circuit B. See Fig. 16. The board receives inputs
from thermistors, transducers, demand limit switch, dual set
point switch, remote-on-off switch, chilled water flow
switch, oil level switch, pump interlock contact, compressor
VFD enable contact, and evaporator heater current sensing
switch, and provides output control to expansion valves, oil
and VI solenoids, evaporator heater contactor, isolation
valves, oil heater relays, customer supplied pump relays,
compressor VFD enable relays, and customer-supplied
alarm and running relays. Information is transmitted
between the SIOB boards and the Touch Pilot module via a
3-wire communication bus or LEN (Local Equipment Net-
work). Connections for the LEN bus are J12 and J13. Each
SIOB board has a 4-position DIP switch bank used for
addressing of the board. SIOB-A is at address 49 and SIOB-
B is at address 50. See below for SIOB board DIP switch
settings. See Tables 6 and 7 for a list of inputs and outputs
for the two SIOB boards.
Auxiliary (AUX) Boards — Two AUX boards, AUX
Board A (address 84) and AUX Board B (address 85), are
installed in each unit. Each of the AUX boards has a set of
jumpers, JP1 and JP2, which must be placed as shown in
Fig. 17. The AUX boards respond to commands from the
Touch Pilot
™
module and send the Touch Pilot module the
results of the channels they monitor via the Local Equip-
ment Network (LEN). See below for AUX board A and B
DIP switch settings. See Tables 8 and 9 for a list of inputs
and outputs for the AUX boards.
