Tectrix Climbmax 150 - No Slack; No Brake

11. 'NO SLACK"
11.1 Test Motor
• Remove the cover (see section 25). Put the climber in the Test Mode (see section 3) and run the motor in both
directions by using the arrow keys. If the motor is not running refer to section 10.5.
11.2 Test Slack Switch
Place the Climb Max in Test Mode (see section 3). Watch the 'CALORIES' LED on the display board while pressing
the slack switch on the motor assembly. The 'CALORIES' LED should be ON when the slack switch is NOT pressed,
and the 'CALORIES' LED should go OFF when the slack switch is pressed. Pre-serial number 166190 ClimbMaxes
(Model 150) require an assistant to observe the 'CALORIES' LED while you press the slack switch. Current models emit
an audible tone in response to the slack switch. (A status indicator also displays 'SLACK' or 'TIGHT' on the readouts).
If the climber passes the slack switch test, but displays a 'NO SLACK' error, the slack switch may be out of adjustment.
Refer to section 27 for slack switch adjustment procedure.
11.3 Bad Slack Switch
If the 'CALORIES' LED (or audible tone) does not respond to the slack switch as described above, turn the climber off.
Disconnect the slack switch cable from the power board assembly (see Fig. 16). Plug the slack switch cable of the
spare motor assembly into the power board without mounting the spare motor assembly and repeat the test. If the
climber now passes the slack switch test, replace the slack switch and slack switch cable. Otherwise, plug the original
slack switch back in and replace the following parts in this order: 1. display ribbon cable (see section 31)
2. power board assembly (see section 29), 3. display board (see section 30).
• 12. 'NO BRAKE'
12.1 Belt
Remove the cover (see section 25). See if the friction belt has worn through or is disconnected. If this has happened
see section 28, Friction Belt Replacement.
12.2 Test Motor
Put the climber in the Test Mode (see section 3) and run the motor in both directions by using the arrow keys. If the
motor is not running refer to section 10.5.
12.3 Test Slack Switch
Test the slack switch as described in section 11.2. If the climber passes the slack switch test, but displays a 'NO
BRAKE' error, the slack switch may be out of adjustment. Refer to section 27 for slack switch adjustment procedure.
12.4 Slack Belt Test
•
If the motor is running and the slack switch is adjusted properly (see section 11.2) turn the Climb Max off and on.
Start climbing to 100 fVmin and stop. Watch the belt as the flywheel slows. If the motor assembly unwinds an exces-
sive amount of belt, check for friction belt wear and belt residue on the flywheel surface. If there is considerable wear
and residue, replace or flip the belt end for end and use Scotch Brite or sandpaper to remove the residue. If the motor
passes the motor test (see section 10.4 and 12.2) and all prior tests have been completed but the motor still gives a
poor response in operation, replace the motor assembly.
