Purpose
The purpose of the DPMP is to
monitor the line voltage supplying single and three phase
systems, providing the opportunity to disconnect equipment if the voltages are outside
of the selectable operational
parameters.
Operation
If the voltages and rotation are
within the selectable set-up
parameters, the DPMP will energize the internal relays, transferring the output contacts. If
the voltages and/or rotation
are outside any of the set-up
parameters, the DPMP internal
relays will not energized.
If the line voltage does not
meet all of the set-up parameters, the Default screen will
toggle between the voltage
screen showing the actual
voltages and words describing
the fault.
During transitions to relays energized or relays de-energized,
the remaining time in seconds
is displayed above the present
relay condition (“ON” or “o”).

Default Set-Up
The default set-up for the DPMP as shipped from R-K Electronics is:
Line Voltage: 480VAC, 3Ø
Over & Undervoltage: ±5%
Trip Time Delay: 5 seconds
Re-Start Time Delay: 5 seconds
Phase Imbalance: 5%
Custom Set-Up
The DPMP uses 4 membrane buttons to allow the customer to change the set-up
criteria for their particular line voltage and preferred parameters. The following
listings show the arrangement and selections available by moving through the
menu choices. The membrane buttons allow for movement right or left with
wrap around to selection criteria and up and down within a selection for specic
parameters.
You can select the set-up parameters with only the supply voltage connected.
Example: From the Default screen (A-B, B-C & C-A voltages with relay status)
pressing the right Arrow will take you to the line voltage selection parameters. If
you want to change the nominal voltage to a dierent voltage, press the Up or
Down arrows. Once you have the line voltage (and number of phases) that you
want displayed on the screen:
1. Pressing either the Right or Left arrow will set the new line voltage parameter
into memory and take you to the next screen, or
2. After 30 seconds of no action, the new voltage parameter will be set into
memory and the screen will go back to the default screen.
2
Example: If you want to change the Re-Start Delay to 3 minutes (default is 5 seconds)
and you are on the Default screen:
1. Press the Right arrow until you get to the Re-Start Delay screen
2. Press the Up button until you have 3 Minutes on the screen
3. Pressing either the Right or Left arrow will set the new Re-Start Delay into memory
and take you to the next screen, or
4. After 10 seconds of no action, the new Re-Start Delay will be set into memory and
the screen will go back to the Default screen.

The DPT is a Digital PercentageTimer.
Operational information is displayed for
easy viewing: tiime remaining till relay
transfer, relay status, running hours &
set-up parameters.
With the supply voltage active, The DPT
will activate the relay output for the
percentage of time selected in set-up.
For total cycle time, you can select either
15 or 30 minutes. On time can be
selected in 5% increments for 5% to
95%.
Manual selection of either continuous On
or Off is available.
Running hours are accumulated based
on the output relay being energized.
