4-8 User Manual
E-STOP Switch Operation
For obvious safety reasons, it is essential that the E-STOP switches at the con-
troller locations and the three E-STOP switches on the pedestal base are always
functioning correctly. It is recommended that you check the switches once a
month.
1. With pedestal#1 in Run mode, press down the E-STOP switch at the con-
troller and verify that the pedestal immediately turns off.
2. Pull up the E-STOP switch to release it.
3. Press Standby/Charge on Pedestal #1 until it latches and then press Run to
power up the pedestal.
4. If you have a second controller, repeat steps 1, 2 and 3 for the E-STOP
switch at the second controller.
5. With pedestal#1 in Run mode, press down the first E-STOP switch on the
pedestal base and verify that the pedestal immediately turns off.
6. Twist the E-STOP switch clockwise to release it.
7. Press Standby/Charge until it latches and then press Run to power up the
pedestal.
8. After the pedestal has initialized, repeat steps 5, 6, 7 for the other two E-
STOP switches.
9. Repeat steps 1 through 8 for the other pedestals.
Collision Bumper Operation
For safety reasons it is essential that the collision bumpers on the pedestal base
are operating correctly at all times. It is recommended that you check the
bumper circuit operation at least once a month.
1. Locate the bumper detector circuit board mounted just below the cable
clamp on the rear of the pedestal. The board has a pot and LED indicator
for each of the four bumpers. All four LEDs should be a steady green. If
not, the circuit must be calibrated as described on page 4-18.
2. Observe the LEDs while an assistant presses firmly on the first bumper
with his hand or foot. The corresponding LED should turn red as the
bumper is pressed and back to green when it is released. If not, the circuit
must be calibrated as described on page 4-18.
3. Repeat these steps for the other three bumpers.
