Additional Product Information
Power Monitor
Wagner Model #: DTP-3
All Vogt Tube-Ice machine models are available from the factory with a three phase line voltage
power monitor with LCD display. The units are also available for after market or retrofit installation.
These units monitor line voltage inputs from 190 to 610 volts and provide protection against line
voltage variances which can damage or destroy the compressor motor. Features include automatic
system shutdown and restart based on current line conditions, a voltmeter, and a non-volatile
system memory so settings are retained even if power is lost. If machine is ordered with this option
the power monitor can be factory set to customer specifications. The Vogt Part number for a power
monitor retrofit kit is 12A7700K01.
The Display
The display normally shows the AB BC CA line voltages.
If the unit is waiting on a timer, that timer will be displayed. The timer display may be switched off by
pressing SELECT. The LCD will then display the normal AB BC CA line voltage pairs.
Pressing the SELECT button once shows the contactor load side voltages (if the load side option is
connected). The display automatically returns to the display of line side voltage after a few seconds.
Press the Select button to step through the parameters. As you step through the parameters, the
selected parameter will flash. Use the up and down arrow keys to adjust to the desired operating value.
