All set parameters (timing, test counts) saved after power loss
-
No reprogramming required after power interruption
5. Presettable Cycle Count with Auto-Stop
-
Set target cycle count
-
System automatically stops and alarms when reached
-
Countdown mode available with system lockout at completion
6. Adjustable Timing Parameters
| Timing Parameter | Range | Description |
|---|---|---|
| Pull-in (Strong Attraction) Time | 0 – 99.99 sec | Initial high-voltage period to open valve |
| Holding (Maintain) Time | 0 – 99.99 sec | Reduced-voltage period to keep valve open |
| Stop (Off) Time | 0 – 99.99 sec | Valve closed, waiting for next cycle |
7. Overcurrent Protection

Test Workflow
The WH-ZJ01-409 follows an automated test sequence:
-
Power ON – Solenoid valve energized
-
Pull-in phase – Strong attraction voltage applied (0-99.99 sec, LED indicator on)
-
Holding phase – Reduced holding voltage applied (0-99.99 sec, LED indicator on)
-
Power OFF – Valve closes
-
Stop time – Wait period (0-99.99 sec)
-
Air pressure detection – Verifies valve opened/closed correctly (optional)
-
Cycle count increment – Counter advances by 1
-
Repeat – Next cycle begins
Applications
-
Self-priming solenoid valve manufacturers – quality control & R&D
-
Gas appliance manufacturers – incoming inspection of valves
-
Water treatment equipment manufacturers – valve durability testing
-
Automotive component suppliers – solenoid valve validation
-
Third-party test laboratories – certification testing
Why Choose WH-ZJ01-409?
