Total, Max And Min Visualization; Logic Functions - Automation Direct ProSense DPM3-P Series User Manual

User Manual - DPM3-P Series Digital Panel Meters
Clear to zero the variable present on display is carried out when releasing the RESET key;
being then reinitiated the count, in counter mode or chronometer, from zero or offset.
The RESET key will not operate if in the program lock-out routine its corresponding
step is activated.

Total, Max and Min Visualization

In tachometer mode one push on the MAX/ MIN key shows, when activated, the total
value in the programmed color; next push shows the peak value with the flashing led MAX
indicator; next push shows the valley value with the flashing led MIN indicator; another push
brings us back to current value indication.

Logic Functions

The connector CN3 provides 3 optocoupled inputs that can be operated from external switches.
Three different functions may be assigned to the inputs using the front panel keys. Each function
is associated to a pin (PIN 2, PIN 3 or PIN 4) that is activated by applying an external switch
closure with respect to PIN 1 or COMMON. Function assignments to the inputs are achieved
through the programming of a number between 0 and 12 corresponding to one of the functions
listed in the following table.
Factory Configuration
As shipped from the factory, the CN3 connector allows remote control of the PROCESS and
TOTAL RESET functions as well as the HOLD function.When a HOLD is made, the display
value remains frozen while the corresponding pin is activated. The HOLD state affects neither
the meter internal operation nor the analog and relay outputs if present.
PIN (INPUT)
PIN 1
PIN 2 (INP-1)
PIN 3 (INP-2)
PIN 4 (INP-3)
The external electronics applied to the CN3 connector inputs must be capable of withstanding
a potential of 40V / 20 mA present at all terminals with respect to COMMON. In order to
guarantee the electromagnetic compatibility please refer to the connection instructions in the
Wiring Terminal section.
