RECORD OPERATING SETPOINTS AND
CONFIGURATION INFORMATION
Before powering down to replace the flashcard, copy
down all of the following operating setpoints and con-
figuration information.
1. Configuration Screen - Page 1
a. Order number
b. Active Remote Control Setting
c. If Active Remote Control = Direct I/O, docu-
ment “type” of Direct I/O selection.
d. Ethernet IP settings
e. Anti-Recycle Settings
2. Configuration Screen - Page 2
a. Compressor Type, Model, Refrigerant
b. Compressor Control Type & number of
Controllers
c. Oil Pump selection
d. Oil Cooling type
e. Motor Current Device
f. Optional Function Selections
3. Configuration Screen - Page 6
a. Optional I/O boards
4. Compressor Control Setpoints – all
5. Alarms and Trips Setpoints – all
6. Timer Setpoints – all
7. Instrument Calibration - Pressure page
a. Record Transducer Range selection for suction
pressure, discharge pressure, filter inlet pres -
sure, oil manifold pressure.
b. Record ‘total offset” value for suction pres-
sure, discharge pressure, filter inlet pressure,
oil manifold pressure
8. Instrument Calibration - Temperature page
a. Record ‘total offset’ for suction temperature,
discharge temperature, oil separator tempera-
ture, oil manifold temperature and process
temperature.
9. Instrument Calibration - Analog Inputs page
a. Record current transformer ratio
10. Maintenance Notes –all
11. Compressor Runtime.
REPLACE FLASHCARD
(Refer to Figure 20 - 4 )
1. Remove power from Vission 20/20 panel.
2.
Remove old flashcard and install new flashcard and
power panel back up.
RE-ENTER OPERATING SETPOINTS AND
CONFIGURATION INFORMATION
1. Log on as “admin” user (default password = admin).
2.
Re-enter all values in Configuration screen. The
most vital thing is is to re-enter the correct com-
pressor type, model and refrigerant. Re-enter the
Compressor Runtime on page 1 of the configura -
tion screen. Make sure you re-select any optional
boards that are installed, and apply those additions.
3. Re-enter all Control Limits
4. Re-enter all Alarm and Trip setpoints. The most vi-
tal thing is - under the “Delay” tab, enter 5 seconds
for all alarm and trip delays.
5. Re-enter all Timer Setpoints
6. Re-enter all Instrument Calibration offsets for pres-
sure transducers. Insure that the Suction Pressure
transducer range is properly selected (typically
0-200psia 4-20ma) – but double check proper set-
ting. In the Analo page – re-enter C/T Ratio.
7. Re-enter Maintenance Notes if desired.
8. You do not need to recalibrate the capacity and vol-
ume actuators.
