Ranger Irrigation Fluid Warming System
English
Model 247 Product Safety Features
The following chart describes the safety alarm features of the Ranger Irrigation warming unit.
note
:
The difference in over-temperature alarm system cut-off points does not indicate any difference
in safety and is simply a result of tighter controller tolerances.
The Ranger Irrigation Fluid Warming System is designed with very tight controls to regulate its temperature
to the 41°C set-point. The microprocessor controller measures the temperature at the fluid pathway inside the
warming plate four times every second, making it very responsive to changes in flow rate.

Primary over-temperature
alarm system
48°C LED alternately displays
“HI” and temperature,
alarm sounds, alarm light
flashes.
Primary Alarm: Alarm
sounds, controller cuts
power to the heaters until
temperature falls below 48°C.
When heater temperature
drops below 48°C, audible
and visual alarms stop.
Independent back-up
over-temperature alarm
system (cut-off).
50°C LED displays the
temperature or has gone
dark, alarm sounds.
Primary failure. Temperature
will rise to 50°C within a few
seconds. The safety backup
system is activated at 50°C
and power is immediately shut
off to the
heating plates.
Under-temperature alarm 33°C LED displays “LO”
and temperature, alarm
