Nice EPMORB - User Manual

The Nice EPMORB / EPMORB/A is a reflective photocell system designed for presence detection in automated gate and door systems. It consists of a receiver-transmitter element (photocell) and a reflector, working together to detect obstacles along the optical axis between them. This device is categorized as a Type D presence sensor according to EN 12453 and is part of the Era-EP series, intended for use with various automation systems for doors, gates, and garage doors. Any use outside of this specified purpose is considered improper and prohibited.

Function Description

The EPMORB / EPMORB/A utilizes "BlueBus" technology, which simplifies connection and communication between the photocells and the control unit (or interface) using only two electrical wires. The connection is made in parallel, and each photocell is assigned a specific function within the automation system by inserting a few jumpers. This technology allows for efficient integration into existing Nice automation systems. The product can also be used in conjunction with "FT210B" series devices, which are also equipped with "BlueBus" technology, to resolve electrical connection issues with sensitive edges on moving door leaves. For the US market, the EPMORB reflective photocell serves as an external entrapment protection device (Type B1 non-contact sensor), compliant with UL 325 requirements, designed to protect individuals from accidental injury by moving gates or doors by disabling the gate's movement.

Important Technical Specifications

• Type of product: Presence detector for automated gates and doors (Type D as per EN 12453 standard).
• Technology adopted: Indirect optical interpolation by means of a photocell and a reflector, with a modulated infrared beam.
• Power supply/output: The device must be connected exclusively to a control unit (or interface) equipped with "BlueBus" technology. Electrical power is drawn from this device, which also receives the output signals.
• Maximum absorbed current: 1 "BlueBus" unit.
• Response time: Under 30 ms.
• Range: Useful range 8 m; maximum range in optimal conditions 15 m. The maximum range may drop by 50% in adverse weather conditions (e.g., fog, rain, dust).
• Detection capacity: Opaque objects larger than 50 mm along the line of sight between the photocell and the reflector (maximum speed 1.6 m/s).
• Protection rating: IP 44.
• Operating temperature: -20°C to +50°C.
• Assembly: Elements facing one another, anchored to two vertical surfaces parallel to one another or to an appropriate column support.
• System for adjusting the alignment between the photocell and the reflector: Yes.
• Dimensions (single element): 105 x 50 x 40 h mm.
• Weight (sum of the two elements): 83 g.
• Installation surfaces: Must be perfectly parallel to one another; slight errors can be corrected with the orientation system.
• Cable length: Maximum 20 m.

Usage Features

The photocells are designed for outdoor use, protected against rain and dust infiltrations, but are not suitable for particularly salty, acidic, or potentially explosive atmospheres. Installation in areas subject to flooding or water stagnation should be avoided. Power cables must enter the photocell through the designated holes in the lower section of its support, inserted from below to prevent water penetration.

The device's proper functioning can be influenced by several factors, including the position of the devices, their proximity to systems lacking interference suppressors, and interference from other similar devices during adverse weather conditions. It is crucial not to install the device too close to the ground or near large metal objects.

The photocells are not primary safety devices but auxiliary safety devices. While built for maximum reliability, they may malfunction or fail in extreme conditions, and this may not be immediately evident. Therefore, it is recommended to observe the following precautions:

• Transit should only occur when the gate or door is completely open and the leaves are stationary.
• Never transit while the gate or door is closing or about to close.
• In case of any malfunction, immediately shut off power to the automation and use manual mode only (refer to the automation's instruction manual). Contact a qualified person immediately to inspect and repair the device.

Maintenance Features

Regular maintenance of the photocells is recommended at least every 6 months. The procedure involves:

1. Releasing the gearmotor manually, as described in the user manual, to prevent involuntary activation of the automation during maintenance.
2. Checking for and removing any humidity, oxidation, or foreign bodies (e.g., insects). If in doubt, replace the equipment.
3. Cleaning the housing, especially the lenses and glass panels, with a soft, slightly damp cloth. Avoid using detergents containing alcohol, benzene, abrasives, or similar cleaning products, as these may dull polished surfaces and hinder photocell operation.
4. Running a functional test as described in the testing chapter of the manual. The product is designed to operate for at least 10 years under normal conditions; after this period, increasing the frequency of maintenance is recommended.
