FAULTS
– Contains records of the last 30 fault events. The most recent
event is displayed when the
Fault
screen is first displayed. After 30
events have been recorded, the newest record overwrites the oldest. Each
record lists an event’s numeric fault code (refer to
Working with System
Faults
on Page 10) plus the date and time at which the event occurred.
Use any of the
Keypad
buttons to scroll through the other fault events.
Press
ESC
to return to the previous screen.
To the right, record #15 shows that a Purge Flow Fault (fault code
<1000>) occurred on 06/07/05 at 12:37.
SILENCE
– Sets the length of time the internal audible alarm is turned
OFF when the front panel
SILENCE
button is pressed. The factory default
is 300 seconds (5 minutes). If the cause of the alarm/fault has not been
cleared at the end of this time period, the internal audible alarm is
reactivated. Use the
Keypad
to enter the desired time period, and then
press
ENTER
to save that value and return to the previous screen.
P-CHK
– This
Pressure Check
function displays the current manifold
pressure and the stored ambient pressure in psia, along with the
difference between these two pressures and the current fault code. Refer
to the heading
Working with the P-CHK Function
on Page 13.
GAS
– Used to select of any one of 31 gas types plus one custom gas for
monitoring. Factory default is R-134A. Note that the factory can program
a custom gas type as specified on the sales order, or a custom gas can be
programmed into the monitor at a later time using the
CUST K1, K2, K3
function. Use the
Keypad
to select the desired gas type, and then press
ENTER
to save the selection and return to the previous screen.
Gases Available for Selection:
R-11, R-12, R-21, R-22, R-23, R-113, R-114, R-123,

– Sets the monitor’s date and time. Use the
Keypad
to enter
the correct date and time, and then press
ENTER
to save those values
and return to the previous screen. Note that time is displayed in a
24 hour format, while the date is displayed as mm/dd/yy.
CAL
– Used to change a calibration factor for a specific gas. Factory
default is 1.000. Refer to the heading
Working with the Calibration
Function
on Page 14.
CUST K1, K2 & K3
– Used to enter custom calibration data for a blend
of refrigerant gases that is not part of the monitor’s standard refrigerant
gas library. Before using this function, the operator must contact the
factory and provide information about the blend of refrigerant gases to be
monitored. Custom calibration data will then be supplied to enable the
monitor to accurately measure that particular gas blend. To enter this
data, refer to the heading
Entering Custom Refrigerant Calibration
Values
