Product Description:
The Danaher made the HZ172A605 Cycl-Flex Count Control, which is a mechanical counting machine with a count range that can be programmed from 2 to 100. The control is made to be mounted on a panel and has a clutch device that reacts to electrical signals. The count control includes a chrome-plated bezel for mounting on the outside and protection to corrosion.
The HZ172A605 Cycl-Flex Count Control is compatible with 120 VAC ±10% at 50 or 60 Hz. On the final power stroke, the clutch moves into the count-out position. Contact behavior changes between stages. Terminals 6-7 are closed when the tally begins, but they reopen when it ends. Terminals 6 through 8 stay closed during the cycle. Contacts A-C remain open, and the most recent count has been completed. Contacts A-B are disconnected during the countdown. Terminals 4-5 and 4-3 control the delay and continuous switching capability. Contacts 9-11 close at count-out, whereas contacts 9-10 stay closed during the count. The clutch coil is linked to terminals 1 and 2. The count setting can only be changed after the clutch is released if it has positive teeth. The count control is used in factory automation to complete repetitive tasks.
The HZ172A605 Cycl-Flex Count Control requires a 3.063-inch diameter cutout with a fitting depth of about 7.19 inches. The mounting hole design features four holes spaced 4.250 inches apart. The neon ignition light on the dial shows that the coil has been energized. The Cycl-Flex Count Control can be adjusted manually or electrically, depending on the wire setup. These dimensions allow for the secure alignment and connection of panels. It is designed to meet the most demanding requirements of its users.
Frequently Asked Questions about HZ172A605:
Q: Does the HZ172A605 Count Control support both momentary and sustained input modes for flexibility?
A: Yes, the unit allows both momentary and sustained input wiring options that support various operation modes like repeat cycle or timed delays.
Q: Why does the HZ172A605 Count Control include a built-in neon pilot light in the dial?
A: The neon pilot light indicates when the clutch coil is energized that helps verify active control operation status.
Q: How does the HZ172A605 Count Control manage contact switching during the full count cycle?
A: The unit uses specific terminal combinations that switch between open and closed states to control load circuits and reset timing.
Q: Do terminals 4–5 in the HZ172A605 Count Control support delayed circuit switching functions?
A: Yes, terminals 4–5 operate in delayed mode that opens at count-out to manage load disconnect timing.
Q: Why does the HZ172A605 Count Control require count setting only with the clutch released?
A: Setting the count with the clutch released ensures gear alignment and prevents internal mechanism damage or miscounting.
