Installation Instructions
MT050C
During the initial pressurization of the transmission line, the dehydrator will cycle every 2 to 4 minutes with the system at
0 psig pressure. The cycle time of the dehydrator will become stable once the transmission system is fully pressurized.
1.4 - Alarms
The MT050C offers Low Pressure, High Humidity (Optional Kit), Excess Run and Power Fail alarms as a standard feature.
In addition, a summary alarm connection is provided on all units. Alarm conditions are indicated on the display. The
alarms are dry contacts and are set for continuity on alarm.
The external alarm monitoring system (supplied by others) is connected to the terminal strip located on top of the cabinet.
A small slotted screwdriver is necessary to make the connections.
The connections to the alarm strip are as follows; refer to Figure 1 and 2 for correct locations and colors of the wires on
the terminal strip.
