Diagnostic LEDs
Reference Drawing:
4 Column MASC LED Driver Specifications ............ Drawing A-166216
There are seven diagnostic LEDs located in the TNMC controller, six indicating
when the controller is receiving signal, and the seventh indicating power status. Four
of the LEDs, those indicating CAN and RS-232 signal functions, are not used with
the TNMC controller. Refer to the drawing listed above for more information. The
following table explains the operation and functions of each of the diagnostic LEDs.
LED Color Function Operation Summary
DS1 Red CL signal Steady on or
blinking
DS1 will be on or blinking when the
driver is receiving signal and off when
there is no signal with CL (current loop).
DS2 Green CL signal Steady on or
blinking
DS2 will be on or blinking when the
driver is receiving signal and off when
there is no signal with CL.
DS3
(Not used
with
TNMC
functions)
Red CAN signal Steady on or
blinking
DS3 will be blinking when the driver is
receiving signal and on when there is
no signal with CAN (controller area
network).
If there is no CAN device connected to
TB1, both DS3 and DS4 will be on and
steady.
DS4
(Not used
with
TNMC
functions)
Green CAN signal Steady on or
blinking
DS4 will be blinking when the driver is
receiving signal and on when there is
no signal with CAN.
If there is no CAN device connected to
TB1, both DS3 and DS4 will be on and
steady.
DS5
(Not used
with
TNMC
functions)
Red RS-232
signal
Steady on or
blinking
DS5 will be on or blinking when the
driver is receiving signal and off when
there is no signal with RS-232.
DS6
(Not used

functions)
Green RS-232
signal
Steady on or
blinking
DS6 will be on or blinking when the
driver is receiving signal and off when
there is no signal with RS-232
DS7 Green Power Steady on DS7 when on and steady indicates the
