3.1 HARNESSING CONNECTORS

All field terminations are brought into the NSM-3E Signal Monitor by means of MIL-C-26482
connectors. The outside harnesses are not interchangeable between any of the 6, 12, or 18
channel monitors as defined by NEMA Traffic Control Systems Specification (TS-1, part 6),
i.e., a 6 channel harness assembly will not mate with a 3 channel signal monitor.

3.2 MINIMUM FLASH DIP SWITCH PROGRAMMING

Programming of the front panel Minimum Flash DIP switches is in a binary encoded format:
MinFlash 8

It is recommended that the Minimum Flash Time be programmed on the NSM-3E Signal
Monitor to exceed the initialization time of all cabinet assembly components following an
AC+ restoration. The amount of flash time is typically equal to the amount programmed on
the controller, so that if the controller fails to execute a minimum flash period, the signal
monitor will serve as a backup to provide the minimum flash time.

3.3 SSM DIP SWITCH PROGRAMMING

The SSM dip switches are labeled "SSM 1", "SSM 2", and "SSM 3". Positioning a switch in
the ON position (to the right) enables a channel for Dual Indication AND Clearance
Monitoring. The corresponding channel dip switch must be placed in the OFF position (to
the left) when an unused Red field output terminal is connected to AC+.

3.4 OPTION DIP SWITCH PROGRAMMING

The NSM-3E Signal Monitor provides seven independently programmed options:

3.4.1 GY ENABLE

Set this switch to the ON position to enable Green / Yellow Dual Indication monitoring. See
Section 2.2.1.

3.4.2 RP DISABLE

Set this switch to the ON position to Disable Recurrent Pulse monitoring, only if needed.
See Section 2.4.
