50 OPERATING INSTRUCTIONS
7/124 - 10/104, 10/124 - 14/114, 14/84
NORMAL OPERATION
The operator may observe and monitor operating parameters using the
MidPort and gauges. In the event the compressor controller detects a
parameter outside normal operating limits, the compressor will alert
and/or shutdown, and display a diagnostic code. In the event the compressor controller detects a parameter at a
dangerously high or low level, the compressor will be automatically
shut down with the cause of the shutdown shown on the MidPort.
TWO PRESSURE MODES OF OPERATION (for 7/124 - 10/104 and 10/124 - 14/114 models only)
Key
A. Separator tank
B. Panel pressure gauge
C. Discharge pressure transducer
D. Automatic blowdown valve
E. Orifice
F. Unloader
G. Start / run solenoid valve
H. Regulator pressure transducer
I. Pressure regulator - Low pressure mode
J. Pressure regulator - High pressure mode (for dual mode models only)
K. Mode solenoid valve (for dual mode models only)
L. Captive pressure solenoid valve
M. Orifice
N. Manual blowdown valve
Dual mode models (7/124 - 10/104 and 10/124 - 14/114) are capable
of operating at two pressure modes:
1. The Low Pressure Mode is activated by pressing the Low Pressure
Button. In this mode, the compressor will regulate
according to the air demand, between 0 and 12 m
3
/min at 6,9 bar
regulated set pressure for the 7/124 - 10/104 or between 0 and
12,7 m
3
/min at 10,3 bar regulated set pressure for the 10/124 - 14/
114. The regulated set pressure of this mode can be changed (see
Pressure Regulating Adjusting Instructions) from 5,5-6,9 bar for the
7/124 - 10/104 or from 5,5-10,3 bar for the 10/124 - 14/114.
2. The High Pressure Mode is activated by pressing the High
Pressure Button. In High Pressure Mode, the compressor
will regulate according to air demand, between 0 and 10,6 m
3
/min
at 10,3 bar regulated set pressure for the 7/124 - 10/104 or between
0 and 11,3 m
3
/min at 13,8 bar regulated set pressure for the 10/124
- 14/114. The regulated set pressure of this mode can be changed
(see Pressure Regulating Adjusting Instructions) from 5,5-10,3 bar
for the 7/124 - 10/104 or from 5,5-13,8 bar for the 10/124 - 14/114.
