Description Choices / Ranges Default Setting
FP
Maximum Fluid Pressure — Maximum allowable fluid
pressure; settable in either PSI or kPa. Should the fluid
pressure rise above the maximum fluid pressure value, the
audio and visual alarms will activate and the compressor,
heater, fan, and pump will turn OFF.
NOTE: The Chiller also incorporates a built in pressure
regulated bypass valve. It will maintain a maximum outlet
pressure by diverting flow of the process fluid to the
reservoir. The bypass valve may be adjusted by the
customer.
CAUTION: Maximum operating pressure for the Chiller is
100 PSI / 6.9 bar. Different pumps have different maximum
operating pressures.
20 to 100 PSI
13 to 680 kPa
(display value x 100)
80 PSI
5.5 x 100 =
550 kPa
FL
Minimum Flow Rate — Minimum allowable flow rate;
settable in either GPM or LPM. Should the fluid flow rate
drop below the minimum value, the audio and visual alarms
will activate, and the compressor, heater, fan, and pump will
turn OFF.
0 and 1.5 to 3 GPM
0 and 6 to 11 LPM
1.5 GPM
6.0 LPM
AF
Auto-Refrigeration Set Point — The upper temperature at
which the refrigeration system will activate; displayed and
settable in °C only. There will be no refrigeration or cooling
at set points above the AF setting.
+20° to 40°C 35°C
Sd
Maximum External / Internal Temperature Differential
(optional) — Establishes the cooling/heating rate when the
remote temperature control probe is installed and enabled.
4° to 20°C 5°C
rP
Ambient Tracking / Remote Probe (optional)
AtC — Ambient tracking probe enabled.
Chiller controls
fluid temperature based on room or machine temperature
(wherever the ambient tracking probe is located) plus or
minus a user-set offset (±5.0°C / ±9.0°F).
rPC — Remote probe enabled.
Chiller controls fluid
temperature based on the process fluid temperature at an
external location.
nO — Ambient tracking / remote probe disabled.
nRP — Ambient tracking probe not installed.
Dependent on option and
software installed.
nAP
C1 / C2
Calibration Offset — Allows adjustment of the displayed
temperature to match that of an independent traceable
standard; displayed and settable in °C only.
C1 — Internal calibration offset
C2 — External calibration offset
±2.9°C 0.0°C
Fc
Flow Rate Calibration — Allows adjustment of the
displayed flow rate to match that of a known standard.
