The ENQ4 electronic alarm system is a compact monitoring and fault detection unit designed to identify and report unacceptable operating conditions. Ideal for industrial applications such as compressors, manufacturing machines, vehicles, and HVAC systems, the ENQ4 features optical displays and a reliable shutdown mechanism for rapid response to faults, minimizing damage and reducing service costs.

Features:

• Efficient Monitoring:
- Four fault detection inputs to monitor operational conditions
- Immediate shutdown via the alarm relay contact (A1-14) during faults
- Wire break detection through external normally closed contacts

• User-Friendly:
- Optical indication with red LEDs for faults and a green LED for operational readiness
- Labeling area for custom identification of fault indications
- Label strips included; series labeling available on request

• Compact Design:
- Panel-mount housing (48x48 mm)
- Splash-proof and dust-proof front panel

• Flexible and Durable:
- Suitable for unshielded input lines up to 100 m in length
- Operating and alarm voltages up to AC 230 V supported
- Multiple ENQ4 units can be arranged side by side in a tableau


Functionality:

• Normal Operation:
- In a fault-free state (all external monitoring contacts closed), the alarm relay contact A1-14 remains closed, and the green LED is illuminated.

• Fault Condition:
- Opening a monitoring contact (S1-S4) activates the corresponding red LED, opens the alarm relay contact A1-14, and facilitates rapid shutdown of the monitored machine/system.
- Memory for sporadic faults; reset by interrupting the power supply.

• Test Mode (S5):
- Closing contact S5 opens the relay contact A1-14; reopening S5 closes A1-14 if no faults are detected.

• Signal Delay:
- A delay of approximately 200 ms at each input and the alarm relay contact filters brief voltage dips.


Mounting and Installation:

• Easy Integration:
- Compact housing for panel mounting (48x48 mm)
- Splash-proof and dust-proof front protection

• Wiring:
- Tolerant of unshielded cables up to 100 m in length
- Alarm relay and test input are easy to configure


Safety Instructions:

• Installation and operation must be performed by qualified personnel only.
• Adherence to all relevant safety standards and regulations is mandatory.

Applications:

• Compressors: Early detection of operational faults
• Manufacturing Machines: Ensures uninterrupted operation
• Vehicles: Monitors critical operating conditions
• HVAC Systems: Protects against malfunctions
