technician the ability to produce all inputs and outputs while
observing the controller operation. The NT-11's portable carrying
case allows the technician to perform his tests on a bench
in the shop or in the field at the intersection. All panel
switches have three positions, on/off/momentary.
Power Interrupt:
The NT-11 has a feature which permits testing the AC
power interrupt operation of a controller. Adjustable from
0.1 to 1.1 seconds. It verifies that the controller responds
correctly to short powerline interruptions.
