7.2.3.2. Screen 2: Date of Installation
On this screen, you may enter the date the compressor
was installed. This date is stored in the module memory for
reference purposes.
7.2.3.3. Screen 3: Customer Code
On this screen, you may enter a three-character custom-
er code number. This code is stored in the module memory
for reference purposes.
7.2.3.4. Screen 4: Compressor Model
This screen enables you to enter a description of the
compressor model the PerformanceAlert™ module is at-
tached to. Press the RIGHT ARROW key to make the cur-
sor appear in Line 3 of the display. To enter text on this
line, for each character use the POINT "." and MINUS "-"
keys to scroll through the alphanumeric characters until the
desired character is shown. Press RIGHT ARROW to
move to the next character. When finished, press DOWN
ARROW to enter the name, and DOWN ARROW again to
save changes and exit to Screen 4.
7.2.3.5. Screen 5: Serial Number
On this screen, you may enter a ten-character string of
text. This code is stored in the module memory for refer-
ence purposes.
7.2.3.6. Screen 5: Setpoints
The DLT TTP is the high temperature setpoint for trip-
ping on high discharge line temperature. When the dis-
charge line temperature is above the DLT TTP setpoint (in
degrees Farrenheit), a HIGH DISCHARGE alert will oc-
cur.
The Severe Alert OFF Time is the minimum number of
minutes the compressor will remain OFF when a trip oc-
curs as a result of an alarm code 1, 4, 6, or 7. When one of
these alarm codes occurs, the compressor will not reset un-
til the Severe Alert OFF Time delay has elapsed.
The LO V STP is the setpoint for low voltage trip. An
voltage below this value will cause a LOW VOLTAGE
alert to occur. This setpoint is a fixed value and may not
be altered.
7.2.3.7. Screens 6 through 8: Lockout Setpoints
For alert codes 1,2,3,4,6, and 7, the LOUT CNT field
with the number corresponding to the alert code number
sets the maximum number of times per day the alert must
occur before a lockout will occur. For example, C1 LOUT
