Item Control Description
1 Main Power Switch Turns system power on and off.
2 SYSTEM ON Turns the lamphead on when STDBY, IDLE, or OFF is displayed. From
OFF, the system goes into WARMUP mode until the filament is warmed up,
then power is applied to the magnetrons and LMPDLY is displayed while
the magnetrons stabilize. LAMPON is displayed when the lamp lights.
3
STANDBY When the Standby button is pressed power is removed from the lamp. The
magnetron filaments remain powered. STDBY is displayed. This mode
allows the system to cycle to curing power faster than from OFF.
Excessive use of Standby mode will shorten magnetron life.
IDLE (if enabled) If the Idle mode is enabled during system configuration, then pressing the
Standby button puts the system in Idle mode. In this mode, the lamp is
powered at a low light and heat state. When SYSTEM ON is pressed, the
lamp will cycle to LMPDLY then to LAMPON.
The lamp should not remain in Idle Mode for longer than necessary. After
10 minutes in Idle Mode the lamp automatically reverts to Standby mode.
4 SYSTEM OFF Turns the lamphead off.
5 NETWORK
LOCAL
REMOTE
Sets system operation to LOCAL mode (system controlled from front panel)
or to REMOTE mode (system controlled by a remote device or controller
through discrete I/O or DeviceNet).
6 LAMPHEAD
AIR PRESSURE
Displays lamphead pressure in X.X inches w.c. (water column).
7 LAMPHEAD
MAGNETRON
Displays the current through each magnetron in milliamps (mA). Pressing
the MAGNETRON button toggles between MAG A and MAG B current. If
the power control mode is configured, then OPC is displayed.
8 POWER SETTING Adjusts the UV output of the lamp, as a percentage of full power. Power
can be adjusted from 20% to 100% while the lamp is in the OFF or ON
state. At 100% the lamp produces the maximum UV intensity it is capable
of (600 watts/inch).
The system is factory set to operate at 100% output. To check the power
level set point, press the SET-SAVE button. In network LOCAL mode, you
can change the output in 5% increments by pressing the UP or DOWN
buttons. Press the SET-SAVE button in order to save your changes and
return to normal operation. In network REMOTE mode, power can be
adjusted in 1% increments by a remote PLC. Regardless of the control
method, changes to the power setting take effect immediately.
Remote Units Controlled by a Master: The remote units determine
their power setting by multiplying the master power setting by the remote
set point (set at the front panel of the remote unit). If the Master power
setting is 80%, then the output of a remote unit set at 50% is actually 40%
of its potential output (80% x 0.5 = 40%).
S The remote unit set point is always the value set from its front panel.
S The Master set point is set from its front panel when it is in Local mode.
In Remote mode it can be set by analog input or DeviceNet.
S All systems can only be set to values between 20% and 100%. If any of
the above cases calculate a value below 20% the control will stay at
40% until the calculated value is again above 20%. This will not set an
error but the unit power will not go below 20%.
