Open Collector Option

Whenever a limit is reached an open collector output provides a 5 Vdc signal at 50ma. on the output connector, e.g... Limit 1 provides its 5 volt output signal between pins 1 and 2.

HOLD FUNCTION

The hold function allows to freeze the Process Variable reading in the display window indefinitely till the Hold pin is active. This function is activated by tying Hold pin (pin13) to the digital ground pin (pin 14) through a relay or switch.

SAVING PARAMETER:

DP3600 saves all the programmed parameters in an EEPROM (electrically erasable programmable read only memory). An EEPROM stores the programmed parameters even when the power is removed from the unit. However, it is important to note that if the parameters are being changed during setup, they must be saved in the EEPROM by pressing and holding RESET key till the display reads ‘SAVING’. If the parameters are NOT saved and the power is removed from the unit, any newly changed values will be lost (the unit will maintain the old values).

POWER

Power connection should be made to the three terminal connector as shown in figure 3. Also, make note that it is very important that the power line inputs and the power ground are not switched. Doing so will permanently damage the instrument. Refer to the drawing for proper connections. For convenience, the printed circuit board is labeled L1 L2 GND on the under side of three terminal power connector.

For instruments with the 12Vdc power option, refer to Figure 3.

NOTE: WHILE MAKING POWER CONNECTION TO THE UNIT, MAKE SURE THAT AC POWER LINE L1 OR L2 IS NOT ACCIDENTALLY CONNECTED INTO THE GROUND (GND) TERMINAL. THIS WILL RESULT IN PERMANENT DAMAGE TO THE INSTRUMENT.

DOUBLE CHECK THE CONNECTIONS BEFORE APPLYING POWER!!
