Timer Limits:

Displaying:

To display timer limits, first push the TIME key. While still in this mode go on to push LIMITS key. The display will briefly show TR1 LT (for timer 1 Limit) and then the previously programmed value. Pushing the LIMITS key one more time will display TR2 LT followed by pre-programmed timer 2 value.

Programming of timer limit values is done during setup procedure (for details look under SETUP). Timer values are can also be displayed without pushing ‘TIME’ key. TR1 LT and TR2 LT is displayed following Process limit 4 (or deviation limit) value, as described above under Process Limits.

Resetting:

The two timer outputs will reset as soon as the time is reset to zero. Time is reset to zero by pushing TIME and RESET keys simultaneously.

ALARM OUTPUTS

Status:

The system has optional process and timer alarm outputs that are activated when the limit is achieved on each one of them. The alarms can be programmed as normally open or normally closed (see SETUP). The status of these is indicated on the front panel by the LEDs. When ever an alarm is activated the respective LED is turned on.

Electro-Mechanical Relay Option:

DP3600 units can be ordered with either open collector outputs or electro-mechanical relays. (Check model number printed on the unit for option). If ordered with relays, then these relays are programmed during Setup to operate as either 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.
