The ENQ4 electronic alarm system provides a compact and comprehensive monitoring solution for detecting unacceptable operating conditions. It is ideal for industrial applications such as compressors, manufacturing machines, vehicles, or HVAC systems. With optical indicators, robust construction, and simple integration, the ENQ4 minimizes downtime and enhances operational safety.

Features:

• Efficiency:
- Maintenance-friendly through optical indicators
- Prevents damage with automatic shutdown in the event of a fault
- Enables comprehensive system monitoring with multiple ENQ4 units in a tableau setup

• User-Friendly:
- Four alarm inputs (S1–S4) with corresponding red LEDs for faults
- Green LED indicates normal operation
- Labeling areas for customized fault identification
- Label strips included; custom labels available on request for series applications

• Flexibility:
- Operating/alarm voltages up to AC 230 V
- Wire break detection via external normally closed contacts
- Supports unshielded input lines up to 100 m in length


Functionality:

• Normal Operation:
- The alarm relay contact A1-14 remains closed in a fault-free state, 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, shutting down the monitored system
- Alarm memory stores sporadic faults; reset by interrupting the power supply.
- Green LED turns off during a fault condition.

• Test Mode (Input S5):
- Closing S5 opens the alarm relay contact A1-14.
- Reopening S5 closes the contact if no faults are detected on S1–S4.

• Signal Delay:
- 200 ms delay on each input and the alarm relay contact to filter brief voltage dips.


Mounting and Installation:

• Easy Integration:
- Panel-mounted enclosure (48x48 mm)
- Splash-proof and dust-proof front panel

• Wiring:
- External normally closed contacts for wire break detection
- Supports unshielded input lines up to 100 m in length


Safety Instructions:

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

Applications:

• Compressors: Monitoring operational issues
• Manufacturing Machines: Ensures uninterrupted operation
• Vehicles: Monitors critical states
• HVAC Systems: Prevents malfunctions
