STARTUP
The following points are to be checked and implemented before
Electricity
- Check for connection to a proper three phase line
voltage connection to the fan for proper performance. Ensure
supply lines to the unit are properly fused and all local electrical
codes are followed.
Pneumatics
- Check that the compressed air is connected.
Compressed air should be clean, dry and oil free and
within a
pressure range of 5 - 6 bar (73 - 87 psi). For best filter
cleaning, set pressure regulator at 6 bar (87 psi).
SET POINTS
Default values enable basic unit operation. Each value should be
given consideration for optimized operation, and can be adjusted
with continued use and experience using the equipment. Consult
Lincoln Electric Field Service to shorten the learning curve.

ADJUSTING PARAMETERS
A)
The following parameters can be adjusted from the main
standby screen (with fan off)
1.
Airflow (SetAirFL): Default is 4000 CFM which is normal for
most applications
2.
Filter Change Alarm Setpoint (Alarm SP): Default is 1500 pa
3.
Filter Cleaning Threshold (SetFltrPr): Default for clean filters
is 500 pa
4.
Filter Hours (FilterHr)
5.
Date/Time (also see DATE/CLOCK ADJUSTMENT)
B)
The following parameters are password (1234) accessible and
should
only be adjusted by maintenance and service personnel.

DATE/CLOCK ADJUSTMENT
1. To adjust the PLC's date and clock settings with the unit in
standby mode, press OK, then arrow down to SET CLOCK and
press OK. Select SET CLOCK again by pressing OK. Change the
date and time, then hit the ESC button to exit.
2. Daylight Savings Time can be set by selecting DST in the SET
CLOCK menu. USA locations with daylight savings time can select
US at this menu.
PERFORMANCE MONITORING
