2.2
TOUCHPADS
Eight touchpads on the overhead Control Panel perform all control functions:
2.2.1
ON / OPERATE / TEST
Whenever this touchpad is pressed, the MT 5500 activates all circuits, initiates a self-diagnosis pro-
gram and places the unit in the Operate Mode. This diagnostic program for instant fault detection
can be activated at any time by touching the OPERATE touchpad. If any faults are ever found, they
will be immediately reported on the LCD display. (See Section 4).
2.2.2
OFF
When this touchpad is pressed, the unit is turned OFF. All information and settings are stored in
memory and the unit is ready to be returned to full operation instantly when the OPERATE touch-
pad is pressed.
2.2.3
COUNTER
When this touchpad is pressed, the traffic count is displayed on the LCD display. Pressing and hold-
ing this touchpad for ten (10) seconds causes the counter to return to zero (0). Whenever the LCD
is displaying information other than the current traffic count, pressing this touchpad will cause the
count to appear along with the Sequence Number of changes that have been made to
Program/Sensitivity settings. CT (Number) and SEQ (Number) will appear. Each time the
Program/Sensitivity Mode (ACCESS touchpad) is accessed, the Sequence Code that appears on
the LCD will be advanced one number. It is recommended that a written notation be made on the
Operations Worksheet (see Section 11.1) whenever this code is accessed, explaining reasons for
the access. If the ACCESS touchpad has been pressed and an improper access code has been
entered, a * will appear before the sequence number (SEQ *37). This indicates that an unsuccess-
ful (unauthorized) attempt has been made to gain access to the Program/Sensitivity setting.
2.2.4
VOLUME
When this touchpad is pressed, the volume level of the unit’s audible alarm will be shown on the
LCD display and the actual volume of the alarm will be heard. The
+
and
-
touchpads can be used
by operators to raise or lower the volume. Press
OPERATE
to return to the operate mode.
2.2.5
+ AND -
These touchpads will be used to increase or decrease various numerical settings and for certain ON
/ OFF functions.
