Operation, TPS3 Control and Diagnostic Display Panel

Operation

TPS3 surge protective devices require minimal attention after installation. TPS3’s contain diagnostic circuits which monitor the suppressor'sstatuscontinuouslyandautomatically.Allphaseindicators and controls are located on the display panel of the unit. Display panels are formatted either for horizontal or for vertical mounting orientation as required for each application.

TPS3 Control and Diagnostic Display Panel

TPS3’s are equipped with a status indicating LED for each phase on the panel. When all LED's are green, the suppressor is on-line and functioning properly. If a fault condition occurs, the audible alarm will sound, the Red Service LED will illuminate and the LED representing the affected phase will extinguish, indicating that the unit needs service. The audible alarm can be silenced by pressing ALARM SILENCE on the touchpad. The audible alarm and Dry Contact can be tested by depressing TEST. If a fault alarm occurs, see Corrective Maintenance (Testing and Repair) for further information.

Display Panel with Surge Counter Option

The surge counter option provides a means to display the total number of transient voltage surge events since the counter was last reset. The counter includes Eprom memory, which retains counter memory in the event of a power loss. The RESET touchpad will reset the counter to zero. The COUNT touchpad increments the counter by one (1) and tests the circuitry for proper operation. If a fault alarm does occur, see Corrective Maintenance (Testing and Repair) for further information.

Figure 9: DISPLAY - VERTICAL (SHOWN WITH SURGE COUNTER)

Phase A, B & C: Green LED indicators—one per phase. Green is good. Extinguished green LED indicates loss of protection. Every suppression element in this SPD is monitored. N-G suppression element monitoring is logic-connected to Phase A.

Service LED (red): LED illuminates in the event of problems. This indicator is logic-connected to the Phase LEDs. Should a Phase LED go out, the Service LED will illuminate and the Audible Alarm will sound.

Test: Tests red Service LED and Audible Alarm, and changes state of Dry Contacts

Alarm Silence: Turns Audible Alarm off. (Alarm is deactivated when the Silence LED is illuminated.)

Surge Counter Count: (if equipped) Increments optional surge counter by one (+1)

Surge Counter Reset: (if equipped) Resets optional surge counter to zero (0)

Dry Contacts Feature

TPS3 01, 05, and 06 units are equipped with dry contacts. This feature provides Normally Open (N.O.) and Normally Closed (N.C.) circuits, which can be used for remote indication of a failed transient voltage surge suppressor. There is only one dry contact output consisting of two electrically isolated sets of NC-C-NO contacts. This dry contact output changes from "normal" to "alarm" if any problem occurs inside the SPD (i.e.: loss of power to any phase, any thermal protector inside the SPD opens, or any fuse inside the SPD opens). The dry contact terminal block is located on the back of the module, opposite side of bus tabs. This connector is designed for low voltage or control signals only. Maximum voltage should not exceed 240 volts and maximum current should not exceed 5 amperes. These contacts may be used to provide a signal to an emergency management system or computer interface board. The relay contact pin arrangement is outlined in the table below.

The Normally Closed (N.C.) configuration is recommended because it will detect a wiring defect, such as a cut wire(s), where Normally Open (N.O.) will not.
