Manual sensor test (special-mode test)
Use this diagnostic test to test the product sensors and switches. Each sensor is represented by a letter
and number on the control panel display. Following is the default state of the sensors when the test is
accessed (J is not used on this product).
●
A1 B1 C1 D1 E0 F0 G0 H1 I0 K0 L1 M0 N1 O0 P0 Q0 R0 S0 T0 U0
NOTE: For the K right and front door interlock switches test: Sensor K displays as 0 when both the
front and side doors are closed. When either door is opened, sensor K displays as 1.
There is only one interlock switch for both doors. If sensor K displays as 1, check both door actuators.
If the actuators are not damaged, check connector J118 on the DC controller.
TIP: If a sensor test fails and the solution is to replace an assembly, try the following. Before you
replace the entire assembly, try replacing the failed sensor with the sensor from a replacement
assembly. If the problem persists, replace the indicated assembly.
1. Touch Administration.
2. Scroll to and touch Troubleshooting.
