Four Character Message Display (LED)
A four-digit, seven-segment display is used under "ordinary" operation to indicate the
"Process Temperature" (PT). In other words, if the system is running, and not
programming, the display will show the current actual system temperature.
If the user is programming the system, the display will alternate a prompt and a value.
If the user is selecting a menu, a menu prompt will alternate with a blank display.
Certain values, including SP and PT, may be forced to a nearest-integer format (
i.e .,
no decimal places displayed) by the DP function (see Etc menu).
If the system is IDLE, the display will show the Reservoir Level.
Fluid Level Indication Symbols
_ _ _ _ Reservoir is Full
_ _ _ Normal Operation Levels
_ _ Fluid Low
_ Critically Low Fluid Level (machine will not run)
Hour Meter
An hour meter is provided on the rear panel. The meter starts and stops with the
pump.
Pressure Gauge and Bypass Valve
An analog pressure gauge on the front panel indicates the pressure of the process
fluid as it exits the chiller. The valve can be adjusted to suit your application. For
example, if pumping to a glass jacketed vessel rated for no more than 30 PSI, then
the bypass valve could be set so the process fluid pressure never exceeds 30 PSI.
