Switch-Dim Functionality

The Switch-Dim interface allows simple dimming using non-latching (momentary) wall switches. Up to 50 LED drivers can be connected to one switch.

Switch Action and Response:

• Short press (<0.4 second): Toggle light on/off.
• Long press (>0.4 second): Toggle dim light / increase brightness.

Synchronization:

• Long press (>15 seconds): All lights will dim down to minimum then return to 50% brightness.

Note: The number of drivers connected to a switch should not exceed 25 pieces. The maximum length of the wires from push to driver should be no more than 20 meters.

1-10V Dimming

The 1-10V input is operable via commercially available simple rotary wall switches or dedicated system central dimming controllers.

Note: If the driver is used with Switch-Dim or interface prior to 1-10V interface, the 1-10V interface may need to be re-set by placing a short circuit across the 1-10V terminals until the light returns to full brightness (approx. 3-5 seconds).

Self-testing Feature

Routine testing of emergency lighting is required by law (IEC62034, EN50172). Hytronik HEM09 / HEM09H models have an internal clock to perform:

• 3-minute functional test every month.
• 3-hour functional test every 6 months.

• Self-test starts after luminaires are connected to an uninterrupted mains supply for over 24 hours.
• Permanently monitors battery and charge condition.
• Dual fault indication via red LED and buzzer.
• Automatic random test to avoid simultaneous testing of adjacent luminaires.

Manual Testing

A test switch performs the following functions:

• Monthly Test / Fault reset (Short push <5s): Green LED flashes once, initiates monthly 3-minute test. Clears any rectified fault indicators.
• 6-month test initiation (Long push >5s <10s): Buzzer beeps twice, battery charges for 24h, followed by a 6-month duration test. Green LED flashes twice every 3 seconds during discharge.
• Full duration test initiation (Long push >10s): Buzzer beeps three times, initiates a full duration discharge. Green LED flashes three times every 3 seconds during discharge.

Bi-Colour LED Diagnostics

Provides status information through LED flashes and buzzer sounds for various conditions:

Tri-level Control (Corridor Function)

This function allows tri-level control for areas requiring light change notices before switch-off. It offers 3 levels of light (100% -> dimmed light -> off) and selectable waiting times.

• With sufficient natural light, the light does not switch on when presence is detected.
• With insufficient natural light, the sensor switches on the light automatically when presence is detected.
• After hold-time, the light dims to stand-by level if the surrounding natural light is below the daylight threshold.
• Light switches off automatically after the stand-by period elapses.

24h Daylight Monitoring Function

This function uses an antenna with a built-in daylight sensor to provide a "smart photocell" function, activated when stand-by period is set to "+∞ ".

Demonstration scenarios show light behavior at different times (21:00, 21:10, 21:40, 08:10, 17:40) based on movement and ambient light.

Settings example: Hold-time: 10min, Daylight threshold: 50lux, Stand-by dimming level: 10%, Stand-by period: +∞.

Manual Override: Allows end-user to switch on/off or adjust brightness via a push-switch.

• Short Push (<1s): on/off function.
• Long Push (>1s): adjust the hold-time brightness level between 10% and 100%.

Note: If manual override is not desired, leave the "push" terminal unconnected.

Semi-auto Mode (Absence Detection)

This mode uses a motion sensor activated by a manual press of a push switch. The light stays ON in presence, dims in absence, and switches off in long absence. This combination saves energy while maintaining efficient lighting.

• The light does not switch on when presence is detected (unless manually activated).
• Short push to activate the sensor and switch on the light.
• The light turns on full, and the sensor stays in sensor mode.
• The light keeps being ON during presence.
• People leave, the light dims to stand-by level after the hold-time.
• The light switches off automatically after the stand-by period elapses.

Note: End-user can choose between manual override or semi-auto mode. Default mode is manual override.

Remote Control Functions (HRC-05)

The remote control (HRC-05) offers various functions:

• Permanent ON/OFF function: Press "ON/OFF" to permanently switch the light on or off, disabling the sensor. Pressing "Auto Mode", "RESET", or "Scene mode" quits this mode. The mode reverts to AUTO after power failure.
• Auto Mode: Sensor functions with the latest settings.
• Reset function: Press "RESET" to return all settings to default.
• Dim +/-: Long press "Dim +" or "Dim -" to adjust brightness during hold-time.
• Test mode: Initiates a test mode (2s hold-time, disabled stand-by period and daylight sensor). Ended by pressing "reset", "scene mode", or "hold-time" buttons.
• Power output: Switches output between 80% and 100% for energy saving.
• Ambient daylight threshold: Sets the daylight threshold by overwriting the previous learned lux value.
• Lux disable: Disables the daylight sensor, allowing motion detection to turn on the light regardless of natural light.
• Manual override / Semi-auto mode: Switches between manual override (buzzer beeps twice) and Semi-auto mode (buzzer beeps once).

Scene mode

Four preset scene modes are available via the remote control:

End-user can adjust these settings using the respective buttons on the remote control. The last setting remains valid.
