The school zone flashing beacons in Longview, Texas (pop 85,000) used a paging system to program school signals. Keith Covington, Traffic Signal Supervisor, determined the system “limited us, not only communicating with the clocks but monitoring the clocks”. ELTEC’s SYSTEM 3000 was chosen to centrally program, manage, and monitor each TC-3000 IP time clock (36 total).
When the SIMA software service was discontinued, remote communication and programming to Spot Devices’ school zones systems was no longer possible; nor was there a means for programming at the pole. For the MODOT (Missouri) Southwest District, ELTEC designed a cost-effective solution while salvaging as many parts as possible. Specifically, the cabinet, battery, charge controller, solar panel, and beacon were reused.
NTC-17E Software ‘Gets Better with Age’
For over 40 years ELTEC has been manufacturing programmable time clocks for the traffic industry. ELTEC’s DLPRO 17E software is used to program the NTC-17E series (AC, DC, 1, 2, or 4 relays) from a computer. Annual programs including all exceptions are downloaded once a year.
ELTEC Introduces Network Based Time Clock
ELTEC has launched a new program-mable time clock, the TC-3000. Using your available internet/network ac-cess, it provides real-time closed-loop management from a host computer, eliminating the need to send techni-cians for on-site trouble shooting or changing/modifying programs.
2-way Paging Used with River Ferry Signs to Alert Motorists
ELTEC’s TC-2000 2-way paging time clock is primarily used to control school zone flashing beacons, but Clackamas County in Oregon uses the system to manage the illuminated “CLOSED” signs, which support the operation of the Canby Ferry on the Willamette River.
