- Display: 4-digit digital display
- Output: 2 Changeover Relays (DPDT)
- Supply Voltage: Up to 240V
- Mounting: Panel mount with 45mm x 45mm cutout
- Connection: Plug-In type
3. Setup and Installation
3.1 Safety Precautions
- Ensure power is disconnected before installation or wiring.
- Installation should be performed by qualified personnel only.
- Verify supply voltage matches the timer's specifications.
3.2 Panel Mounting
- Create a panel cutout of 45mm x 45mm.
- Insert the timer into the cutout from the front.
- Secure the timer using the provided mounting clips from the rear of the panel.

4. Operating Instructions
4.1 Power On
Once wired and secured, apply power to the timer. The digital display will illuminate, showing the current time value or a default setting.
4.2 Understanding On-Delay Function
In On-Delay mode, the timer's output relays will activate only after a set time period has elapsed, following the application of a trigger signal or power. The timer counts up or down, and once the set time is reached, the DPDT relays change state.
4.3 Programming the Timer
The timer features four programming buttons located below the display. Refer to the detailed programming guide in the product's full technical documentation for specific steps to set timing ranges, time values, and operating modes. Generally, the buttons allow for:
- Mode Selection: Choosing between different operating modes (e.g., On-Delay).
- Parameter Adjustment: Setting the desired time value (0.001s to 9999h).
- Unit Selection: Selecting time units (seconds, minutes, hours).
- Start/Stop/Reset: Initiating or resetting the timing cycle.
The 'LOCK' indicator on the display signifies if the timer's settings are locked to prevent accidental changes.
5. Maintenance
- Cleaning: Use a soft, dry cloth to clean the timer's display and casing. Avoid abrasive cleaners or solvents.
- Inspection: Periodically inspect wiring connections for tightness and signs of wear or damage.
- Environment: Ensure the operating environment remains within specified temperature and humidity ranges to prolong the timer's lifespan.
6. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Timer not powering on | No power supply; incorrect wiring | Check power connections and supply voltage. Verify wiring against diagram. |
| Output relays not activating | Incorrect time setting; no trigger signal; timer in 'LOCK' mode | Verify programmed time and mode. Check trigger signal. Unlock timer if necessary. |
| Display shows error code | Internal fault; programming error | Refer to the full technical manual for specific error codes. Try resetting the timer. |
If issues persist, contact Crouzet technical support.
