Start up:
When the system is connected to power, the PLC will enter a 20
second initialization to ensure that the dryer is functional and ready to
operate. The PLC will count down from 20 seconds.
When the PLC finishes initialization, it will display the Home screen
shown below.
Line 1:
Number of total run hours accumulated.
Line 2:
Number of total system cycles accumulated.
Line 3:
Number of cycles on dryer column #1.
Line 4:
Number of cycles on dryer column #2.
Note:
New systems will be shipped with several cycles on each of the
columns. This is because the unit is tested before it leaves the factory.
When the
selection button is pressed, the PLC will display the
recommended service interval and total system run hours accumulated:
Line 1:
Recommended service interval.
Line 2:
Number of total run hours accumulated
When replacement service is carried out on the dryer, the dryer
run counter (Line 2) can be reset by depressing the first 2 selection
buttons
and
on the PLC at the same time. This must be done
for 15 seconds to reset the dryer run time counter.
WARNING: Reconfiguring the factory settings on the PLC is
not recommended. This will result in the dryer not functioning
properly and void the warranty.
ADDITIONAL WARNINGS:
Unless the directions below are followed and authorized JUN-AIR
parts are used, physical injury or property damage may result.
The following additional warnings must be noted;
•
The dryer is only suitable for installations with nominal voltages
equal to that stated on the dryer rating label.
•
The dryer is designed to operate at pressures between 4 barg
and 12 barg. It is not suitable for pressures in excess of 12 barg.
•
Only connect pneumatic equipment suitable for the maximum
pressure indicated.
•
The dryer is designed to operate with inlet temperatures
between 0 and 50°C (32°F and 122°F).
•
Product servicing should only be carried out by authorized JUN-
AIR distributors.
•
The dryer should be protected against rain, moisture, frost and
dust.
•
Contact between the dryer and any chemicals, solvents or
paints must be avoided.
•
Ensure system is switched off and disconnected from power and
the system fully depressurized before attempting to access the
serviceable components of the dryer.
•
Only 3/8 BSPP fittings should be used. Use of any other fittings
will result in damage to the pressure vessel components.
•
The dryer exhaust ports cannot be fitted with any silencing
devices. The exhaust fluids must be expelled into the drain
bottle supplied by JUN-AIR through the tubing provided. The
performance of the dryer will be reduced if the exhaust ports
are restricted.
