CHAPTER 2: Troubleshooting
2.3 No power to the console
Symptom:
No power to the console.
2) Solution:
a. The adapter for this model is 12V - 5A. Check to make sure the power adapter on the unit is cor-
rec
t. Test the power adapter in a known good outlet. Replace the adapter if it is defective.
b. Check the connection of the console cable at the console (Fig1). Unplug the console cable from
console, and use a multi-meter to check the voltage through the console cable. Pin 1 or 2 and pin 7
or 8. it should be 12VDC. If no voltage is present, the console cable is defective, replace it.
c. If the voltage through the console cable is 12VDC, the console is defective, replace it.

CHAPTER 2: Troubleshooting
2.4 Heart Rate/Quick Keypad Issue
Symptom: Heart Rate Function Does Not Work or is Reading Incorrectly
Quick Key Function Does Not Work or Works Incorrectly
Solution:
A. Heart Rate:
1.The heart rate grips are not connected properly or are defective.
With a multi-meter set for DC voltage, plac
e one terminal on each of the HR grip plates.
(Fig1) The
HR g
rip should give a voltage reading of between 0.5 and 2.0VDC
. If the voltage is not between 0.5
and 2.0VDC, remove the 3
screws holding the HR grip together and check the conne
ction of the HR
grip wiring.
2.The heart rate grip wiring is
damaged or not connected correctly.
Check continuity of the HR grip wiring.
Place one terminal of a multi-meter set for resistance on the HR grip wiring at the HR grip, and the
other terminal on the HR grip wiring at the console. An ohm reading of around 1 should be expected.
If the reading is higher than 1, replace the HR grip wiring.
3. The HR board is damaged
Remove the
console. Remove the 6 screws holding the front of the console to the rear. Check the
connection of the HR board wiring to the UCB. If all the wiring is intact and has good contact, replace
the HR board.
4.The UCB is damaged.
If the HR board, HR
grips, and HR grip wiring do not solve the issue, replace the UCB.
B. QUICK Key ISSUE
The keypad connection wires are not connected properly or are defective.
With a multi-meter set for ohms, place one terminal on quick key
slot red wire (Fig2) .the others terminal place one connection slot (fig3). It should read 0 ohms. If not . It mean wire damage. Replace
new console wire.

then plug it in again.
2. Check
theconnection wire between MCB and Induction Brake/generator. Unplug the connection wire
between the quick key pad and console. Be sure not to mix up the right and left quick key
connection wire ends. See U-1X-F (Fig1) and R-1X-F (Fig1 & Fig-2)
