TM 5-3895-374-24-1GP470FA5.OUT 1 or 2: Indicates the controller output relay has been energized to drive the damper actuator. OUT 1 closesand OUT 2 opens the exhaust damper. Note that these outputs are not functional when the HOLD light is on orMANUAL operation has been selected.6.[SET UP]: Places the controller in the configuration set up mode. Scrolls through set up groups and enables the[FUNCTION] key to access parameters within each group. The DC200E instrument has been factory configuredby Hauck and should not require field adjustment, except as noted in these instructions.7.[FUNCTION]:Used in combination with the [SET UP] key to display and select functions within the set up groups.Also used to toggle between local and remote setpoints or between two local setpoints when so configured.8.[DISPLAY]:Allows viewing of local setpoints (SP or 2SP), remote setpoint (RSP), deviation (DEV) or output(OUT) values. Also used to exit the set up mode and return the controller to its normal operating mode.9.[]:Used to increase the setpoint, or change configuration values.10.[]: Used to decrease the setpoint, or change configuration values.POWERA power OFF-ON rocker switch is located on the rear panel of the DPS controller assembly. A 5x20mm 10 Amp fuseprotects against overloads and short circuits.HOLDFor aggregate drying applications, it is normally desired to hold the exhaust damper in its fully closed position until after theexhaust fan has been started. The DPS control system incorporates a hold relay and circuitry for this purpose. Thecontroller will remain in the hold mode and the HOLD light will remain on until 120Vac is supplied to DPS terminal 41.Power from terminal 41 of Hauck’s BCS control panel may be used for this purpose as it remains powered after theexhaust fan limits are closed. DPS terminal 3 is the neutral for the hold circuit relay and should be connected to BCSterminal 3 when used in this manner. A jumper is installed between terminals 7 and 10 to ’hold’ the exhaust damper in theclosed position. This jumper may be repositioned between terminals 6 and 10 if it is desired instead to hold the damperopen. Note that the DPS system is not operational until after the hold relay is energized.MANUALThe DPS controller manual mode is activated by an alternate action pushbutton. When activated, the OPEN and CLOSEpushbuttons will be illuminated and may be used to drive the damper actuator. Note that the manual mode is notoperational until after the hold relay has been energized and the HOLD light is extinguished.(page 3-39)
