1. Introduzione
This manual provides detailed instructions for the safe and efficient operation of your Eurolite 70064224 ESX-4R Switchpack. The ESX-4R is a robust 4-channel DMX switchpack designed for controlling various lighting fixtures and electrical devices in stage and event environments. It features four Type F output sockets, DMX512 input and output, and a maximum total current capacity of 16A.
Please read this manual thoroughly before initial use and keep it for future reference. Adherence to these instructions is crucial for proper function and safety.
2. Istruzioni di sicurezza
Sicurezza generale:
- Questo dispositivo è destinato esclusivamente all'uso professionale.
- Assicurarsi che il dispositivo sia collegato a una presa di corrente dotata di messa a terra.
- Non esporre il dispositivo a pioggia o umidità.
- Scollegare l'alimentazione di rete prima di effettuare operazioni di pulizia o manutenzione.
- Non utilizzare il dispositivo se il cavo di alimentazione o la spina sono danneggiati.
- Tutte le riparazioni devono essere eseguite da personale di assistenza qualificato.
- Assicurare un'adeguata ventilazione attorno all'unità per evitare il surriscaldamento.
Sicurezza elettrica:
- The maximum current per channel is 5A. Do not exceed this limit.
- The maximum total current for the unit is 16A.
- The device uses triac switching. Be aware that a small residual voltage may be present on the output even when a channel is switched off. This can cause low-energy devices (e.g., some LED bulbs) to glow faintly or flicker. This is a characteristic of triac-based switching and not a defect.

- DMX IN (XLR 3-pin): Connects to a DMX controller or the preceding DMX device.
- DMX OUT (XLR 3-pin): Connects to the next DMX device in the chain.
- Potenza in ingresso: Standard IEC power connector for mains power supply.
4. Configurazione e installazione
4.1 Montaggio:
- The ESX-4R Switchpack can be placed on a flat surface or mounted in a rack using appropriate mounting hardware (not included).
- Ensure the mounting location is stable and provides adequate ventilation.
4.2 Collegamento all'alimentazione:
- Connect the supplied power cable to the power input on the rear panel of the ESX-4R.
- Plug the other end of the power cable into a suitable grounded mains power outlet (230V AC, 50Hz).
- Ensure the circuit breaker on the front panel is in the "ON" position.
4.3 DMX Connection:
- Connect a DMX cable from your DMX controller's output to the DMX IN (3-pin XLR) connector on the rear panel of the ESX-4R.
- If chaining multiple DMX devices, connect a DMX cable from the DMX OUT (3-pin XLR) of the ESX-4R to the DMX IN of the next device.
- For optimal signal integrity, terminate the last device in the DMX chain with a DMX terminator.
4.4 Connecting Loads:
- Connect your lighting fixtures or other electrical devices to the CH1-CH4 output sockets on the front panel.
- Ensure that the total current draw for each channel does not exceed 5A and the total current for the entire unit does not exceed 16A.
5. Funzionamento
The ESX-4R Switchpack operates by receiving DMX512 signals from a DMX controller. Each of the four channels corresponds to a DMX channel, allowing you to switch connected devices on or off.
5.1 Setting the DMX Address
The DMX address determines the starting channel for the ESX-4R on your DMX universe. The ESX-4R requires 4 DMX channels (one for each output). If you set the starting address to 1, then Channel 1 will respond to DMX channel 1, Channel 2 to DMX channel 2, and so on.
- Premere il tasto ESC button to enter the main menu if not already there.
- Utilizzare il UP or GIÙ buttons to navigate to the "ADDR" (Address) setting.
- Premere ENTRARE to select the address setting.
- Utilizzare il UP or GIÙ buttons to adjust the DMX starting address (from 1 to 512).
- Premere ENTRARE to confirm the new address.
- Premere ESC per uscire dal menu.
5.2 DMX Channel Control
Once the DMX address is set, the ESX-4R will respond to DMX signals:
- Each channel (CH1-CH4) corresponds to a sequential DMX channel starting from your set DMX address.
- When the DMX value for a channel is above a certain threshold (typically 128-255), the corresponding output channel will switch ON.
- When the DMX value is below this threshold (typically 0-127), the corresponding output channel will switch OFF.
- The channel status LEDs on the front panel will indicate the current state (ON/OFF) of each output.
5.3 Important Note on Triac Switching
The ESX-4R utilizes triac-based switching for its outputs. This technology is efficient but has a characteristic where a very small residual voltage may remain on the output even when the channel is commanded OFF. For most traditional incandescent loads, this is imperceptible. However, for highly sensitive or low-power devices such as certain LED lamps or some types of relays, this residual voltage can cause them to:
- Glow faintly when switched off.
- Flicker intermittently when switched off.
- Cause small relays to activate or larger relays to hum.
This behavior is inherent to triac switching and is not a malfunction of the device. If this effect is undesirable, consider using devices designed for zero-cross switching or incorporating a dummy load (e.g., a small incandescent bulb) in parallel with the sensitive load to dissipate the residual voltage.
6. Manutenzione
6.1 Pulizia:
- Disconnect the device from mains power before cleaning.
- Use a dry, soft cloth to clean the exterior of the unit.
- Non utilizzare detergenti liquidi o solventi.
- Periodically check ventilation grilles for dust accumulation and clean as necessary to ensure proper airflow.
6.2 Sostituzione del fusibile:
The unit is protected by an internal circuit breaker. If the breaker trips, disconnect all loads and reset it. If it trips repeatedly, consult a qualified technician.
7. Risoluzione Dei Problemi
| Problema | Possibile causa | Soluzione |
|---|---|---|
| L'unità non si accende. | No mains power; tripped circuit breaker; damaged power cable. | Check power connection; reset circuit breaker; replace power cable if damaged. |
| No DMX control / Channels not responding. | Incorrect DMX address; DMX cable issue; DMX controller not sending signal; DMX chain not terminated. | Verify DMX address setting; check DMX cable connections; ensure DMX controller is active; add DMX terminator to the last device. |
| Connected LED lights glow/flicker when OFF. | Characteristic of triac switching (residual voltagE). | This is normal for triac switchpacks with sensitive loads. Consider using a dummy load or a different type of switchpack if this is unacceptable. |
| Circuit breaker trips repeatedly. | Overload on one or more channels; short circuit in connected equipment. | Reduce load on channels; check connected equipment for faults; consult a qualified technician. |
