Air supply volume too low. Increase
air volume.
Air supply pressure too high. Do not
exceed 100 psi (0.7 MPa, 7 bar).
Keypad display shows 8 2.02*
* or current software revision.
See setup level 7.
Air supply volume too low. Increase
air volume.
Continuity Checks
Follow the procedure on page 87 to access the circuit
board, keypad, or schematic panel ribbons to conduct
the continuity tests. Be sure to put on the ground strap
provided before checking continuity.
Use an ohmmeter to check continuity on the ribbon
cable for the desired light or key. Refer to the following
charts and Fig. 93 for the associated pin numbers and
locations.
NOTE:
When closed, the keys should have less than 100
ohms resistance.
Check the lights for continuity with the leads touch-
ing the pins one way then reverse polarity. If there
is no continuity reading with either check, the lights
are bad and the entire part needs to be replaced.
SCHEMATIC PANEL KEY AND LIGHT CONTINUITY CHECKS
NOTE:
The keys use the small ribbon (A). The lights use the large ribbon (B). Refer to Fig. 93.
