micro-trak MT-2400 LR, Справочное руководство

Страница: 49 / 52

Your MT-2400 is factory calibrated to operate the standard
M-T Electric Servo Valve. The system is also capable of
using standard 12-volt control valves in place of the M-T
Electric Servo Valve. However, the factory setting will not
allow standard 12-volt control valves to function at peak
performance. You need to activate the special 12-volt control
driver to ensure optimal performance.
When the system will be used in English mode, the rotary
selector MUST be turned to TOTAL AREA when activating the
12-volt servo mode. When the system will be used in Metric
mode, the rotary selector MUST be turned to SUB AREA when
activating the 12-volt servo mode.
Activating the 12-volt servo mode also defaults all of your
calibration settings to the factory settings. BEFORE activating
the 12-volt servo mode, write down ALL of your calibration
settings. Then you can simply re-enter them after activating
the 12-volt servo mode.
To activate the 12-volt control driver, turn the power to the
console OFF. Turn the rotary selector to the appropriate
position (TOTAL AREA for English mode or SUB AREA for
Metric mode). Press and hold the CAL, RESET and “+”
buttons on the front panel and while continuing to hold the
three buttons switch the power to ON. Once powered up,
release the three buttons. A “V” will be illuminated on the
display to indicate that the special control driver mode is
active. To “lock-in” the special 12-volt control driver mode
you must enter calibration. Press and hold the CAL button
until “CAL” lights on the display and the RED warning light
is illuminated (approximately three seconds). The console
is now in calibration mode and the 12-volt control driver
mode is “locked-in”. Because this procedure also restores
factory calibration values, you must re-calibrate the system
for your application. Adjust all necessary calibration values
and exit calibration by pressing and holding the CAL button
until the RED light turns off (approximately three seconds).
The console will remain in the special 12-volt control driver
mode, even when power is turned off.
NOTE: Do not operate system with M-T Electric Servo Valve
installed when the 12-volt control driver mode is activated.
Damage to the servo valve will result.
OPERATIONAL NOTE: Many of the 12­volt control valves on
the market operate very slowly from fully closed to fully open.
The MT­2400 may operate sluggishly or be slow in control
response time. For optimal performance, the control valve
should be installed in a return line with a throttling valve
installed.
