Produkt overview
The FW Murphy EGS21T-250-12 is a robust temperature SWICHGAGE featuring a UV stabilized lens and a screw-on mounting clamp case. It provides accurate temperature readings and includes a normally open contact for switching applications.
The device is designed for panel mounting and utilizes screw terminals for secure electrical connections. Its compact dimensions make it suitable for various industrial and automotive applications.
Opsætning og installation
Follow these steps for proper installation of the EGS21T-250-12 SWICHGAGE:
- Panelforberedelse: Cut a suitable opening in the mounting panel for the gauge. Refer to the product dimensions (4 x 4 x 4 inches) for appropriate sizing.
- Montering: Insert the SWICHGAGE into the prepared opening. Secure it using the screw-on mounting clamp case. Ensure the gauge is firmly seated and stable.
- Elektriske forbindelser:
- Identify the screw terminals on the rear of the unit (refer to Figure 2).
- Connect the 12 VDC power supply to the appropriate terminals. Observe polarity.
- Connect the normally open contact to your control circuit as required.
- Ensure all connections are tight and secure to prevent intermittent operation or damage.
- Sensorplacering: Ensure the temperature sensing element (not explicitly shown but implied by "Temperature SWICHGAGE") is correctly positioned to accurately measure the desired temperature.
- Endelig kontrol: Before applying power, double-check all connections and mounting to ensure everything is correct and secure.
Betjeningsvejledning
The EGS21T-250-12 Temperature SWICHGAGE operates automatically once properly installed and powered.
- Tænd: Apply 12 VDC power to the unit. The gauge needle will indicate the current temperature.
- Temperaturovervågning: The gauge continuously monitors the temperature within its range of 0-250 degrees Fahrenheit.
- Skiftefunktion: The internal switch (normally open contact) will change state when the monitored temperature reaches a factory-set or user-adjustable (if applicable, not specified here) threshold. This can be used to trigger alarms, shut down systems, or activate cooling mechanisms.
- Aflæsning af måleren: Read the temperature directly from the dial (Figure 1).
Opretholdelse
The FW Murphy EGS21T-250-12 SWICHGAGE is designed for minimal maintenance. However, periodic checks are recommended:
- Rensning: Gently wipe the UV stabilized lens with a soft, damp cloth to remove dust or debris. Do not use abrasive cleaners or solvents.
- Tilslutningskontrol: Periodically inspect electrical connections for tightness and signs of corrosion. Re-tighten screw terminals if necessary.
- Fysisk inspektion: Check the mounting and casing for any signs of damage or wear. Ensure the gauge remains securely mounted.
- Kalibrering: This unit is factory calibrated. If you suspect inaccurate readings, contact FW Murphy customer support for assistance. Do not attempt to recalibrate the unit yourself.
Fejlfinding
If you encounter issues with your EGS21T-250-12 SWICHGAGE, refer to the following table:
| Problem | Mulig årsag | Løsning |
|---|---|---|
| Gauge not responding / No reading | Ingen strøm eller forkert ledningsføring. | Verify 12 VDC power supply is connected correctly and active. Check all screw terminal connections for tightness. |
| Unøjagtig temperaturaflæsning | Sensor improperly placed or damaged. Unit out of calibration. | Ensure the temperature sensor is correctly positioned and making good contact with the medium being measured. If problem persists, contact FW Murphy support. |
| Switching function not working | Incorrect wiring of the contact. Temperature not reaching threshold. Faulty contact. | Verify wiring of the normally open contact to your control circuit. Confirm the temperature is actually reaching the set point. If still not working, contact FW Murphy support. |
| Physical damage to lens or casing | Stød eller forkert håndtering. | Discontinue use if damage compromises safety or function. Contact FW Murphy for replacement parts or service. |
