The DPS3301 also functions as a rate monitor, indicating instantaneous as well as average rate of temperature change. Programmable time base allows the rate to be displayed in per second, minute, hour or any other interval.

DISPLAY HOLD FEATURE: DPS3301 offers a display hold feature. When ever pins 13 and 14 are shorted together (e.g. through a remote switch), the reading taken at the time of shorting is frozen on the display. The unit will continue displaying this value until the short is removed.

For the five keys there are five digits --- 1,2,3,4,5. Pass-code is a combination of these digits and for DPS3301 units the pass-code to program new parameters is 3254. Three attempts at entering the correct pass-code are allowed.
'PROGRAM CONTROLLER' MODE Display Time On entering Program Controller mode, the very first step lets you program is the display time. This determines the length of time (in seconds) that any VALUE is displayed before message, such as ‘PROCESS’ is flashed. The unit will first show 'dSPLy t' (for Display Time), and then the current setting in seconds.
Cold Junction adjustment: After setting Heat/Cool mode, the next parameter is the cold junction reference temperature adjustment. The display will first show 'COLd JN' , and then the cold junction temperature will be indicated. Use ‘^DIGv’ key to adjust until the display reads the proper temperature.
NOTE 1: The unit must be powered up for at least ten minutes before any adjustments are made. NOTE 2: For calibrating units with RTD or Thermistor inputs, connect the source to input connector, dial in a temperature near high end of the scale and adjust gain potentiometer on the back of the unit (See figure 7 for reference).
‘^DIGv’ key to increment/decrement the flashing digit. Configure Timing Mode DPS3301 is equipped with 2 versatile timers that may be programmed to operate in 3 different modes, referred to as Timer Mode 0, 1, or 2.
energized. In Mode 1 the timer is ON for a programmed amount of time after a temperature limit is reached (limit1 for Timer 1 and Limit 2 for Timer 2). When programmed amount of time has elapsed, the timer is de- energized.
RATE DPS3301 monitors rate of change of temperature per programmed time base and can be displayed by pushing the ‘DATA’ key (time base is programmed during SETUP procedure). The unit is capable of displaying instantaneous (calculated over the last time base period) as well as average rate of temperature change.

limit alarms. (Check model number printed on the unit for option). If ordered with relays, then these relays are programmed during Setup to operate as Normally Open (NO) or Normally Closed (NC). The default setting is Normally Open. Each of these limit relays provides a switched output whenever a limit is reached. The maximum rating for a 120Vac unit is 120Vac @ 0.5 amp or 28 Vdc @ 1.0 amp.
To display Timer #1 value, push the TIME key twice. The first push shows elapsed time, while the second push will first display 'tr1 Cnt' (for Timer1 Count) and then Timer 1 value. To display Timer #2 value, push TIMER key three times. First two pushes display elapsed time and timer 1 value respectively, while the third push brings up timer 2 value on the display.
HIGH AND LOW PEAKS A useful feature provided by the DPS3301 system is its ability to track high and low temperature peaks. This function is useful if a process must be left unattended for a long period of time, and it is necessary to find temperature extremes during the unattended period.
‘SIGNAL CONNECTOR’ in figure 4. Also indicated are the input signal’s positive and negative polarities for thermocouple connection. These markings are also on the printed circuit board in front of the connector. Care should be taken to connect the positive and negative legs of the signal source to the proper terminals on the connector.
It operates from 100vac to 240vac. This power supply provides power not only to the internal electronics and relays but has up to 20watts (5vdc) available for external applications by the user. Direct Interface to Relay-URM 400/800 DPS3301 TERMINAL COMPARTMENT Page...
