This screen should always be displayed when maintenance items and setpoint items are not being performed. The date on the screen is updated every ½ second. Status information such as Alarms and Trips are displayed on the screen. This Screen contains buttons to navigate to setpoint, setup and maintenance screens.
Set Up Screen From the Main screen, touch the Setup button. After entering an authorized user name password, the screen pictured below will appear. ·Operator Name – This is the same list that appears in the login dialog. Names in this list can be selected for deletion. To change a name or password, you delete the name and enter a new name/password pair. The VILTER operator name cannot be deleted.
Set Up Screen · Anti-Recycle – The operator can select from the following AntiRecycle options: True, Accumulative, Modified, or Hot Starts. These select the strategy used to prevent excessive start/stop cycles of the compressor. Timers and counters used to enforce anti-recycling are adjusted and monitored in the Compressor Timer Settings screen, reached from the Menu screen. Help for the Timer Settings screen explains how the different settings and strategies operate.
Set Up Screen Log On, Off,or Save Changes Press Log on/Save Button and the above screen will appear. When altering setpoints, log on is necessary. Select appropriate user name and enter password to change setpoints. This screen is also used to backup and save setpoints by pressing (Backup Settings). After performing a “Back up Setting” operation, DO NOT power down the Vission/Vantage panel for atleast 1 minute. This will allow adequate time to insure all setpoints have been properly stored.
Maintenance Screen Touch Here From the Main screen touch the Maintenance button. “Service Item Required” message indicates that the compressor runtime hours has accumulated to a value - or a point- where service Maintenance is required. >From the main screen, press the “Maintenance” button. A chart will be shown to indicate what service is required - based on the number of hours the compressor has run.

The Service Button from the Maintenance Screen will bring you to this screen. When entering service items that were completed, make sure to check all items that are listed to be done at that service interval.
Menu Screen At the bottom of the Main screen touch the Menu button to bring up the screen shown in Figure below. Use this screen to navigate to the other setpoint screens contained within the program. Each screen has a help button to describe the function of the screen.
Common Buttons A. Common Buttons There are several buttons that are common for all menu screens: · Return to Menu – This button always returns you to the Menu screen · Logon To Edit – The user is allowed to view data at all screen levels but cannot edit data until a login has occurred. In order to logon, press the arrow next to user name, select user then press the abc button, the key pad screen will appear. Enter your password and hit OK.
Compressor Control Level 1 Access – Compressor Control Setpoints From the Menu screen , press the Compressor Control setpoints button. The compressor control setpoints screen will be shown. These screens enable the operator to view and adjust settings that affect compressor control.
Compressor Control Setpoints on this screen: · · · · Suction Pressure On/Off – The compressor will automatically cycle ON and OFF at the setpoints entered. Suction Pressure On/Off control is only active if the Compressor Control Via Suction Pressure option is selected on the Setup screen. If a compressor shutdown is desired on a suction pressure drop and a manual reset is required, set the OFF value below the Low Suction Pressure Safety Trip value.
Additional Compressor Controls · · High Discharge Pressure Unloading Setpoints 1&2 – Active in Suction Pressure or Process Temperature Capacity Control mode. These setpoints limit the compressor from loading at high discharge pressure conditions. They override the Suction Pressure or Process Temperature Capacity Control setpoints. The capacity of the compressor will decrease when the discharge pressure is at or above the ON set point.
Compressor Control · Oil Separator Heater Temperature – This control limit determines when the oil separator heater is energized. A decrease in oil separator temperature below the ONsetpoint energizes the oil separator heater. On an increase in oil separator temperature above the OFF setpoint, the oil heater is de-energized. · Oil Pump Restart – To determine the ON and OFF values for the pressure ratios, take the absolute discharge pressure (PSIA), and divide it by the absolute suction pressure (PSIA).
· Low Suction Pressure Load Limit – Active in Discharge Pressure Capacity Control mode only. These setpoints limit the compressor from loading at low suction pressure conditions. They override the discharge pressure capacity control setpoints. When the OFF setpoint is reached (at or below setpoint), the compressor will not be allowed to load any further. If the suction pressure continues to fall, the capacity of the compressor will decrease when the suction pressure is at or below the ON set point.
Compressor Alarm and Trip · · Low Suction Pressure Setpoints 1&2 – This is the low suction pressure safety. This safety is active in both temperature and pressure control modes. An alarm or trip will be active on a drop in suction pressure below the setpoint value. · High Discharge Temperature – This is the high discharge temperature safety. The alarm or trip will be active if the discharge temperature should rise above the setpoint value.
Compressor Alarm and Trip setpoint. The alarm or trip will be active if the oil temperature of the separator drops below the setpoint value. · Low Oil Injection Temperature – This is the low oil injection safety. The alarm or trip will be active if oil injection temperature drops below setpoint value after a time delay (Oil Injection Temperature Safety Changeover). · High Oil Injection Temperature – This is the high oil injection temperature safety.
Compressor Setpoints and Alarms · · Prelube Oil Pressure – If the oil pressure does not rise above the reset setting for a time exceeding the Minimum Compressor Prelube Time and the pump runs longer than the Prelube Pump Time Limit, an alarm or trip will occur. These time limits are set on the Compressor Timer Setpoints screen. Prelube oil pressure is defined as the amount that the oil pump drives manifold pressure above the discharge pressure. Low Oil Pressure – This is the running oil pressure safety.
Compressor Timer Setpoints To change a timer setting, you must “Logon to Edit” first. Push the “Set” button then push on the timer setpoint value you wish to change. After the setpoint is changed, press the “Refresh” button. This will refresh the “Current” window, which shows the elapsed time of the timers. · Capacity Decrease At Start – At compressor startup, the capacity motor is held at minimum position for this time period.
Compressor Timer Setpoints · Minimum Compressor Prelube Timer – This is the length of time the oil pump will run after establishing the Prelube Oil Pressure, to prime oil circuit before starting the compressor. · Oil Pressure Bypass At Compressor Start – This timer bypasses the Low Oil Pressure limits. The timer starts when the compressor starts. After the timer has cycled, the Low Oil Pressure setpoint is active.
Compressor Timer Setpoints The compressor restart options (Hot Starts or Anti-Recycle Timers) are selected from the Setup screen. One additional Anti-Recycle Timer that can be selected from the Setup screen is the Modified Anti-Recycle Timer. · Modified Anti-Recycle Timer – Normally, this anti-recycle timer will function as a True AntiRecycle Timer.
