ROUBLESHOOTING

CAUTION!

There are no user serviceable parts within the M3645P. If you are still
experiencing problems after you have reviewed this whole section, you
may contact Bonitron for additional assistance at (615) 244-2825.

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 unit.

▪

If the power lamp will not come on, it is likely that the unit 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.

VERVOLTAGE DURING BRAKING

If an attached drive trips on overvoltage, it typically indicates the M3645P is
not regenerating. There are some simple things that can determine the
cause.
