Antennas Mounted on Water Towers Support School’s IP Time Clocks

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).

Eltec System 3000

Eltec’s SYSTEM 3000 was chosen to centrally program, manage, and monitor school zone signals in 36 locations. A LANG 3000 was mounted at the top of three local water towers.

After reviewing available communication options to the Traffic Center from each LANG 3000 (gateway), it was determined to use the Water Department’s Ethernet connections. By utilizing three water towers, “reaching all our areas without spending a lot of money and without having a monthly bill” was doable according to Keith.

The water tower Ethernet connection is located at base of each tower. To avoid coax signal loss, LANG 3000’s (enclosed in a small cabinet) were installed on the top of the water towers. CAT 5 cable from the tower base to the top provides power and data communication. Doing so eliminated approximately 100 feet of coax cable ensuring maximum transmit power at the antenna. The 1 watt, 900 MHz spread spectrum radio didn’t lose signal strength by doing it this way.

After installing four gateways, one of the LANGs could not ‘see’ one school’s beacons due to hills and trees. Locating the fourth LANG to an intersection controller cabinet with a fiber connection, enabled them to utilize the system’s repeater capability resolving the problem. Two intermediate clocks were programmed to create and support a communication pathway. According to Keith “by installing the LANG in the intersection controller cabinet in the area of communication difficulty, the redirection of repeating signals (clock to clock) came easily when trying to maintain communication back to the Traffic Center.”

The DLPRO 3000 software is “easy to use and user-friendly.” He continues, “Having the capability to connect and monitor each clock individually and quickly determines if lights are flashing with great accuracy. It’s a valuable tool of communication compared to the old system.” Monitoring all clocks at a glance is also an option with the Background Monitor function. With the former paging system, “you couldn’t validate if lights where flashing or not without going directly to the site or someone reporting it.” The SYSTEM 3000 “allows the opportunity to fix problems before they are noticed by the public through the DLPRO 3000 monitoring feature in the software.”

Solutions for Spot Devices’ School Beacons (IMSA Jan/Feb ’15)

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.

A voltage booster circuit was integrated inside ELTEC’s TC- 18 programmable time clock. The circuit board converts the 5 VDC solar panel and battery to 12 VDC powering the TC-18 time clock and LED. By simply mounting the clock inside the cabinet and connecting four wires, MODOT was back in business.

All TC-18 time clocks include a built-in DC flasher and operate on either AC or DC (solar). The keypad allows direct on- site programming, but it is computer programmable using the DLPRO 18 Software.

Every TC-18 is upgradable to become a TC-3000 time clock, an IP/network clock for remote programming and communication. All Spot Devices’ school zone systems have the option of being retrofitted with the TC-3000.

DLPRO 17E Software updates Mar-Apr ’10

NTC-17E Software ‘Gets Better with Age’

Acr38522693595560-2631
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.

The NTC-17E time clock has always had the op-tion of being password protected. Now, the DL-PRO 17E software has a new security feature. The improved version offers password protection for modifying programming. The system administrator determines who has permission to change existing schedule(s). Up to 5 individuals can have the privilege. Once logged in, the user has the authority to overwrite/change a program. Personnel not given permis-sion can still upload and download schedules to and from clocks, but changes to the schedule are not permitted. With-out a password, personnel can save a different program as new, but cannot replace any existing schedules.

Additionally, the enhanced DLPRO 17E software now prints programs for all “Program Names” with one “click” (selec-tion). Previously, only a single “Program Name” would print at a time.

System 3000 Network Based Time Clock (IMSA July-August ’10)

ELTEC Introduces Network Based Time Clock

lang-3000tc-3000a

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.

The System 3000 (DLPRO 3000 soft-ware, LANG 3000 & TC-3000 time clock) utilizes the internet or private intranet and RF technology eliminat-ing paging or cellular fees. No radio repeaters are required. System com-munication is established over the net-work utilizing a secure dedicated port on the host computer and an on-site local area network gateway (LANG). A spread spectrum RF virtual private network (VPN) is created between the LANG and its’ associated TC-3000 time clocks.

The system provides immediate 2-way communication, real-time monitor-ing and control, displaying clock and LANG status. At any time, a single clock, group of clocks or all clocks can be interrogated to verify status. Email messages are sent to the technician(s) on-call as well as other designated individuals to report low voltage con-ditions, any manual overrides or com-munication faults.

The System 3000 controls the opera-tion of beacons based upon program schedules downloaded by the user into non-volatile memory. All programs are stored in the time clock as well as the LANG. Should there be a system inter-ruption, the flashing beacons continue to operate as scheduled. It operates as a stand alone time based control-ler, allowing it to be used anywhere a time based relay output controller is required.

The TC-3000 time clock has an internal flasher, and it’s equipped with two independent output relays for other needed circuits. Both the TC-3000 time clock and LANG 3000 operate on either 12VDC (solar) or 120VAC.

The DLPRO 3000 software runs on Windows operating systems.
