Product Description:

The HZ171A607 from Danaher is a timer with an enclosed dial motor that works on 120 VAC and 50/60 Hz. It has a mechanical dial lock and a modular design that makes it easy to add to systems that need precise time control.

The HZ171A607 timer is equipped with a toothed clutch that must be removed in order to modify the timepiece. Modular systems are composed of the clutch, gear set, shaft sleeve, switch actuator, terminal ring, and mounting plate. The timer can perform both instantaneous and delayed touch functions. When the device is reset, terminals 6-7 and A-C remain open, while terminals 6-8 and A-B remain closed. At a count of 0, 9-10 and 4-3 close, while 9-11 and 4-5 open at a count of 0. The clutch coil will activate the brilliant pilot light that is integrated into the dial. During both the counting and count-out stages, the clutch coil remains powered on. The back terminal block is configured with 12 terminals that are numbered and three terminals that are designated A, B, and C. This HZ171 timer can be utilized with six distinct electrical configurations. There are modes for automatic repeat and reverse start, as well as sustained and transient control switches.

The front face of the HZ171A607 timer measures approximately 4.12 inches by 4.65 inches, and the total depth is approximately 7.19 inches. The design includes a mounting plate with a specified configuration of cutouts and apertures for easy integration. The dial mechanism is protected and locked in place by a clutch device that is controlled by the terminals. Terminal assignments provide a different system for controlling operations that occur immediately.

Frequently Asked Questions about HZ171A607:

Q: Do the terminals on HZ171A607 support multiple wiring configurations for different control modes?

A: Yes, the terminals support various diagrams. These include momentary start, sustained control, repeat cycles, and reverse start, allowing adaptable control functions.

Q: How does the built-in neon pilot light function on the HZ171A607 timer unit?

A: The neon pilot light indicates the clutch coil status. It turns on when the coil is energized during the count phase.

Q: Why do terminals 4-3 and 9-10 close at zero count on HZ171A607?

A: These delayed contacts activate specific circuits at count completion. It helps trigger controlled actions at precise intervals.

Q: Does the HZ171A607 clutch coil stay energized during both counting and count-out stages?

A: Yes, the coil remains energized in both phases. This ensures smooth operation and uninterrupted timing transitions.

Q: How do the modular components of the HZ171A607 support easier maintenance or replacement?

A: The clutch, gears, shaft sleeve, and other parts are modular. They allow quicker service and individual part replacement without disassembling the entire unit.
