Table 4-1 CoolWave 2 Displays and Controls
Item Control Description
1 Main Power Switch Turns the main power on and off to the CoolWave system.
2 SYSTEM ON Turns the lamphead on after the magnetron filament is warm and LMPDLY
is displayed and then LAMPON.
3
STANDBY Applies warm-up power to the magnetron filament and the message
WARMUP appears in the display while warming up. Once it is warm,
STDBY appears.
Excessive use of Standby will shorten magnetron life.
IDLE (if enabled) Allows a low power state used to rapidly cycle the lamp from curing power
to an inactive, low light and heat state.
The lamp should not remain in Idle Mode for longer than necessary. After
10 minutes in Idle Mode the lamp will revert to Standby.
4 SYSTEM OFF Turns the lamphead off.
5 NETWORK 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 XX inches w.c. (water column).
NOTE: The digital display does not display the decimal point in the air
pressure readout. For example PR 83.3 = 8.3 in. H

7 LAMPHEAD
MAGNETRON
Displays the current through each magnetron in milliamps. Pressing the
MAGNETRON button will scroll MAG A and MAG B and display the current
for each magnetron. If the power control mode is selected, then OPC is
displayed rather than current.
8 POWER SETTING Use to adjust the UV output of the lamp. The power setting is an
approximation of the UV output of the lamp, as a percentage of full power.
It can be adjusted from 40% to 100%. At 100% the lamp will produce the
maximum UV intensity it is capable of. At a setting of 50% the lamp will
produce approximately 1/2 of what it does at 100%. Values less than 100%
are only approximations and actual measured values may be higher or
lower depending on the bulb type and the radiometer used to take the
measurements.
The system is factory set to operate at 100% output. To check the power
level set point, press the SET-SAVE button. Change the output in 5%
increments by pressing the UP or DOWN arrow buttons. Changes take
place as soon as you press the arrow buttons. Press the SET-SAVE button
in order to save your changes and return to normal operation.
NOTE: The slave units determine their desired value by multiplying the
master desired value (current power value the master is operating at) by
the slave set point value (value input from front panel of the slave unit). If
the Master power setting is 80%, then the output of a slave unit set at 50%
is actually 40% of its potential output (50% of 80% = 40%).
S The slave set point is always the value set from the front panel of the
slave unit.
S The Master set point is set from the front panel when it is in Local mode
but it can be set by analog input or DeviceNet when in the Remote
mode.
S All systems can only be set to values between 40% and 100%. If any
of the above cases calculate a value below 40% the control will stay at
40% until the calculated value is again above 40%. This will not set an
error but the unit power will not go below 40%.
