DESCRIPTION

The DP3600 series of instruments are micro-processor based intelligent monitors that are capable of performing several tasks in addition to displaying the process variable. The micro-processor technology used in the system design has provided these instruments a cost and performance edge that is simply not possible with analog systems.

Various process parameters monitored by the system can be displayed by pushing appropriate keys on the front panel e.g. LMT1, Peak etc. The respective parameter will be displayed for as long as the key is kept pressed. Alternatively, if the key is pressed and then released, the monitor will display the particular parameter briefly and then go back to process variable display mode. Each key works either by itself or in combination with other keys to perform various functions.

The system has a warning mode where it displays 'HELP' any time a wrong key or sequence of keys is pressed. Also incase of over/under range the 'HELP' sign will be displayed constantly.

The system has six limit alarms, four for process and two timers. One of the four process limits can be figured to work as rate limit (LIMIT 3) while another process limit (LIMIT 4) can be programmed to work s deviation limit. All limit alarms can be operated in two different modes. The first one is non latching mode in which the relays reset automatically as soon as process, rate or deviation falls below the limit (minus the relay dead-band). The second one is latching mode. In this mode the relays will stay energized even after the parameter falls below the programmed limit. They can be reset manually only.

The very first thing required before monitoring the process would be to configure the personality of the unit to fit your particular application. This will allow the process variable to be read in a more comprehensible manner. Configuration is done by going into the SETUP mode and programming such parameters as SCALE, OFFSET, RELAY DEADBAND etc.

SET UP

Setup Entry:

To get into setup mode, press the TIME/SET UP key twice. This will get you into the setup mode and will be indicated by displaying of the message ‘ENTR PC’ (for ‘Enter PassCode’). At this point enter the pass code for your system. The pass code entry, which is four digits long, keeps unauthorized personnel from changing system parameters. Each key is marked with a small digit in one of its corners. Pass-code is a combination of these digits and for this system it is 3254. Three attempts at entering the correct pass-code are allowed. Any time a wrong digit is entered the display will read 'HELP'. If a person fails to enter correct pass-code in three attempts, the system automatically exits SETUP mode. To try again, you have to get into the setup mode by pushing ‘SETUP’ key twice.

Setup Exit:

To exit SETUP mode at any point, simply push RESET key and hold it till display reads 'SAVING' (SAVING indicates that programmed parameters are being saved in Electrically erasable programmable read only memory -- EEPROM).
