•Before each se, inspect the monitor testing cables for damage, s ch as broken connector hoods, or damaged wire
ins lation.
•D ring monitor testing, the testing cables carry 120V AC power. Using damaged cables, or cables not s pplied by
ATSI, co ld res lt in damage to the tester or monitor, and potentially lethal electric shock.
•The PCMT-8800 has no ser serviceable parts. Under no circ mstances sho ld the ser attempt to open the
enclos re. If the tester appears to be malf nctioning, contact ATSI to make arrangements for repair.
Testing Known Bad Monitors
Monitors which have been s bjected to lightning strikes or other severe electrical stress co ld ca se damage to the
PCMT. If yo s spect a monitor has been s bjected to a lightning strike or similar electrical stress, it is recommended that
yo first check the monitor o t in the shop, in a sim lated signal environment, or on a man al tester. In this test set p,
internal monitor shorts will merely blow f ses - on the PCMT it co ld res lt in internal tester damage which will req ire
ret rning the tester to ATSI for repairs.
Non-NEMA Monitors
If yo are performing NEMA tests, be certain that the monitor is NEMA-compatible. Some non-NEMA monitors se a
NEMA-type connector, with non-NEMA wiring. This co ld ca se damage to the tester or to the monitor itself when power
is applied. If yo are not s re if yo r monitor is NEMA compatible, contact the monitor man fact rer.

3. Introd ction
3. Introduction
The PCMT-8800 performs comprehensive testing of vario s types of conflict monitors to ens re that they are f nctioning
in accordance with the req irements of the applicable p blished standard. The following monitor types may be tested:
NEMA TS1 3, 6, 12 18 Channel
NEMA TS2 (MMUs) 12 or 16 Channel Mode
NEMA TS2 MMU 8 Channel (Canada)
System 170 Type 210 16 or 18 Channel
System 2070 Type 2010 16 Channel
LADOT Model 2018
Operating the PCMT-8800 req ires the Test Manager Software to be installed on a comp ter r nning Microsoft Windows
XP or later. The comp ter controls the testing seq ence by sending commands to the PCMT over a USB connection. The
PCMT provides inp t signals to the conflict monitor and verifies that it responds correctly to sim lated conditions that may
occ r in a traffic signal control cabinet.
PCMT-8800 Tester shown with TS2 Cables.
C stom cables are req ired for each monitor type that is tested.
The PCMT may be sed as a bench-top nit, or it may be mo nted in a standard 19" rackmo nt enclos re. For m lti- nit
systems, one comp ter can control m ltiple PCMTs to enable sim ltaneo s testing of many monitors. An optional
carrying case is also available for those sers who m st perform field testing of monitors.

5. Preparing to Test
5. Preparing to Test
5.1. Setting Up the PCMT
To set p the PCMT for testing :
1. P t the On / Off switch located on the front of the PCMT in the Off position.
2. Connect the USB B-Type end of the USB cable to the port on the back of the PCMT.
3. Connect the USB A-Type end of the USB cable to yo r comp ter USB port.
4. Connect the monitor cable connectors to the correspondingly labeled female connectors on the front of the PCMT.
5. DO NOT t rn the On / Off switch to the On position ntil the monitor connectors are connected to the monitor (See
Preparing the Monitor to Test).
5.2. Preparing the Monitor to Test
On both NEMA TS1 and NEMA TS2 monitors, ens re that the program card is blank when r nning a basic Certification
test. Refer to Monitor Switch Settings for additional help with the conflict monitor's extended feat re switches.
System 170 Model 210 monitors sho ld not have any diodes c t (permissives) or Yellow inhibits on the programming card
for Certification Testing. If yo r agency inhibits the Yellow monitoring f nction for walk signals or for all channels, yo
sho ld still test the monitor with a "clean" programming card for Certification Testing. This will res lt in a record that all
monitor f nctions described in the standard were working on all channels at the time of the test.
For all monitor types, if yo choose to r n the optional Permissive Tests to verify a programmed intersection card, yo will
be prompted by the software to change the card at the beginning of the tests.
Once yo have verified that the monitor settings are correct, pl g the monitor cable circ lar MS style connectors into the
corresponding connector on the monitor (NEMA monitors) or insert the monitor into the monitor cable edge card connector
(210, 2010 monitors). Finally, verify that the PCMT has been set p as described in Setting Up the PCMT and then yo
may t rn the On / Off switch located on the front of the PCMT to the On position. At this point, yo sho ld hear fo r beeps
from the PCMT.
Note : If yo do not hear fo r beeps when the PCMT power is t rned on, there may be a problem with the nit. Refer to

7. Test Descriptions
7. Test Desc riptions
All of the PCMT-8800 tests described below are based on the p blished standard that is listed. It is the intent of ATSI to
test all of the req irements of the listed standard as thoro ghly as possible. The tests are based on o r best interpretation
of the standards and are s bject to the limitations of what is practical and feasible in a sim lated testing environment.
Each individ al j risdiction (i.e. state, co nty, city) may have specific req irements or practices that are ro tinely followed
which deviate from the applicable standard or ignore certain parts. F rthermore, some monitor man fact rers may have
certain feat res enabled or disabled in their devices to accommodate s ch deviations from the applicable standard.
Therefore, the ser has the option of disabling certain tests. These tests are listed as “optional” in the Test Set p window.
There may also be certain tests that are related to monitor f nctions that deviate from the applicable standard. These
deviations my be d e to special feat res that have been added and are not yet covered in the standard. There may also
be cases where monitors are old and have been man fact red according to the req irements of a previo s version of the
applicable standard. In s ch cases, special tests may be provided to accommodate these deviations from the c rrent
version of the standard. It is the responsibility of the user to determine what tests are appropriate for their local
requirements.
