TEMS

Check the fan periodically for debris, and blow out with an air hose if it has become
obstructed or not running at full capacity.

Power should not be applied when

ROUBLESHOOTING

CAUTION!

There are no user serviceable parts within the M3645 regen unit. If you
are still experiencing problems after you have reviewed this whole section,
you may contact Bonitron for additional assistance at (615) 244-2825.

5.3.1.

POWER

,

OR

IGITAL

D

ISPLAY IS NOT ACTIVE

:



Check AC input voltage at terminals. Voltage should be within range
specified in Table 2-1 for your unit. If the power light will not come on,
check any overcurrent devices or disconnects upstream of the regen.



If the power lamp will not come on, it is likely that the regen is damaged
and needs to be repaired.

5.3.2.

READY

OUTPUT WILL NOT CLOSE

The  Ready  output  indicates  that  the  module  is  enabled  and  in  a  ready
condition.  When the power is applied to the module, the Ready output will
normally close after a startup delay of approximately 2 seconds.  Thereafter,
the  Ready  output  should  be  closed,  indicating  that  the  system  is  ready  to
operate.    If  the  Ready  output  fails  to  close,  one  of  several  faults  may  be
indicated.



Make sure the Power LED is on.
If the Fault LED is blinking, refer to Table 4-1

, “Blink Codes” to determine

which fault is active, or look at the digital display.



If the Fault LED is on solid, the "Enable" input is not activated.

5.3.3.

U

NIT WILL NOT RESPOND TO

ENABLE

COMMAND



Confirm that 24V is present between TB2-2 and TB2-4 (see Figure 3-6).



If the internal 24V supply is being used, confirm that a jumper is present
between TB2-4 and TB2-5 (0).

VERVOLTAGE DURING BRAKING

If the attached drive trips, it typically indicates the regen is not operating.
There are some simple things that can determine the cause.



Make sure the regen has power and is enabled. The Ready output will
close if the unit is ready to operate. (4.5.2)
