APPENDIX C – DIP SWITCH SETTINGS (900430-1/900461-x)
The TMS 3000 is equipped with a modular processor board and the TMS 2000 is equipped with a Main System board
located in the (left side) electrical non-intrinsically safe compartment of the console where power and control devices
are handed. These boards are supplied with dipswitches that have been factory set. Switches are centrally located
near bottom of the processor card housed in a small rectangular Red enclosure (marked S1). The switches are
numbered 1-4.
Note: Switch positions should not be field modified unless the TMS is first powered-down. All switches are set
CLOSED at the factory and would rarely need to be changed.
Dip Switch Function/Condition:
Switch # 1: With the rocker arm in the OPEN position, this switch activates the System Error Handler and will
produce an audible annunciator and a visual intermittent flashing display for variety of TMS system alarms, warnings,
or error conditions. The TMS continuously scans for system faults. Errors may be printed automatically if printer is
enabled. The audible annunciator and visual intermittent flashing Error message may be acknowledged via Front
panel or Edit enable buttons.
Note: If a printer is not supplied with the TMS, a hardcopy of the condition(s) will not be available. The user may
choose to CLOSE the rocker arm switch, which will allow the intermittent Error messages to continue until the
condition is corrected.
Switch # 2 With the rocker arm in the OPEN position, this switch activates the System Motion Band Symbol,
producing a lower case horizontal line to the right of the Tank I D #. This visual display represents movement of
product in the tank for either Deliveries, Sales, or Thefts. Any of these conditions will be logged as a function of the
motion band sensitivity setting, which is user programmed in the CONFIG menu, PROBE submenu. This symbol will
disappear from the display within 3 minutes after the tank contents has settled and stopped moving. The motion band
symbol will also be present on system power up. The audible annunciator will not be activated during this condition.
Switch # 3 With the rocker arm in the OPEN position, this switch activates the TMS Communication Security feature.
This feature is used when a pass code is desired to prevent unauthorized access when communicating with the TMS.
This switch works in conjunction with the Security setting found in the Header menu.
Switch # 4 With the rocker arm in the CLOSED position, this switch activates the System Watch Dog feature. This
switch is utilized for factory servicing only and should not be changed in the field. In the CLOSED position, neither
the audible annunciator nor a visual intermittent flashing message is activated by the Watch Dog condition.
