The pressure gauge will also reflect a pressure
between 0 and 5.0 psig while the output flow
is between 0.2 and 0 SCFM. The pressure
gauge senses pressure beyond the flow control
orifice and will show the actual pressure in the
waveguide.
During the initial pressurization of the
transmission line, the dehydrator will cycle
every 2 to 4 minutes with the system at 0 psig
pressure. As the dehydrator pressurizes the
system, the cycle times will increase until the
dehydrator output is balanced with the system
leak, at which point the cycle times will stabilize.
1.4 Triple Alarm Option
This optional assembly is designed to provide
the additional Excess Run, High Humidity and
Power Fail alarms to CommScope Dehydrators.
All alarms are Form C dry contacts and are
factory set for continuity at alarm.
The external alarm monitoring system (not
included) is connected to the terminal strip
located behind the cover. A small slotted
screwdriver is necessary to make the
connections.
The connection to the alarm strip is as follows,
and refer to Figure 1 for correct locations and
colors of the wires on the terminal strip.

Alarm Definitions:
Low Pressure:
If system pressure falls significantly below the
low-pressure trigger point, the low-pressure
alarm sensor will activate an alarm contact.
This alarm is an indication of a significant
system leak or a dehydrator failure.
Excess Run:
User settable run time to be set in accordance
with the normal run time for the particular
application. Selectable times are 10, 30, 120
and 240 minutes. See Figure 2 for location of
JP3.
Power Fail:
Activates when power is removed from the
dehydrator. This includes turning the power off
at the switch.
High Humidity:
Activates when system or dehydrator output
humidity rise above 7.5% relative humidity.
At initial installation, this alarm will continue
to alarm until the system has been properly
purged.
