1. Safety Instructions and Safeguarding

1.1. Installation Note

An external mains adapter is required for the electrical supply of the speed controller EPH 526. If this mains adapter is supplied with a voltage >50V DC or >75V AC, the following points must be considered:

The unit should only be installed by qualified specialist personnel.
Installation and operation must comply with local regulations for electrical installations, as well as health and safety regulations.
Protection of people and property must be ensured by applying currently applicable safety regulations (VDE, electrical safety regulations, IEC, etc.).
High start-up currents can occur when a controller device/mains adapter is turned on due to the charging process of the intermediate circuit. An effective safeguard is required on the mains input side (e.g., a C-Rated 16A line circuit breaker).
The use of RCD circuit breakers before the control unit/mains adapter is not recommended due to leakage currents generated by EMC interference suppressing devices.
The regulator card/mains adapter must not be operated without an effective connection to earth. The earth connection must comply with local regulations.

1.2. ESD-Protection / Hazard Note

Attention during installation of the electronic board! It must be ensured that there is sufficient ESD-protection.

Attention during installation	Danger to burn - Beware!	Danger to fire - Beware!	Danger to life - Beware!
It must be warranted on your part that there is sufficient ESD-protection.	Parts of this controller card can reach a temperature up to 80°C. Increased risk at controller cards without protective cover.	Unprofessional handling and installation can cause a fire.	Parts of this controller card are under intermediate circuit voltage and remain energised >50VAC respectively 75VDC after turning main power off. Coming into contact with the terminals, lines, and unit parts can cause serious injuries or result in death!

2. Getting Started with DLR24/20-526 with 15/4-pole Spring Clamp Terminal

Select modes:
- Jumper 1 on 1-2 for internal speed reference value (potentiometer 1) or on 2-3 for external speed reference.

5. Connecting

5.1. Control Connections

Speed ref. value: terminal 11: 5V DC, terminal 12: wiper external potentiometer (10kOhm), terminal 13: GND
Controller enable 1: terminal 15: Input 5-36V DC
Controller enable 2: terminal 16: Input 5-36V DC
Speed ref. enable: terminal 18: Input 5-36V DC
Motor direction: terminal 19: Input 5-36V DC
Output 1 (ready for operation): terminal 9: turns on voltage 10V-36V DC (<50mA), when the controller is ready.
Output 2 (Overload): terminal 10: turns on voltage 10V-36V DC (<50mA), when the current is longer than 3 sec. at the current limit. Resettable by selecting 0V at speed reference value (terminal 12) or disabling speed reference (terminal 18).

5.2. Connecting Diagram

The connecting diagram illustrates the terminal layout and connections for the DLR 24/20-526 unit. The terminals are numbered 1 through 19. Key connections include:

Terminals 1 (UE1) and 2 (GND): Power supply input (DC or AC).
Terminals 3 (motor+) and 4 (motor-): DC motor connections. Motor wires should be shielded and the shield connected to PE (Protective Earth).
Terminal 5: +5V output.
Terminals 6 (encoder line A) and 7 (encoder line B): Optional encoder connections (2 lines).
Terminal 8: GND for the encoder.
Terminal 9: Output 1 (ready for operation).
Terminal 10: Output 2 (Overload).
Terminal 11: +5V output.
Terminal 12: Input for speed reference value (e.g., external potentiometer 10kOhm or 0-10V DC).
Terminal 13: GND for speed reference.
Terminal 14: +5V output.

herewith declares that the product:

Product: 4-Q motor control unit digital
Type: DLR 24/20/X – 526

is conform to the mentioned EC-regulation in connection with the test peripheral devices:

Regulation 2014/30/EU – electromagnetic compatibility (EMC-regulation)

The following harmonised standards were conducted:

DIN EN 55011 VDE 0875-11:2011-04 (EMI emission)
DIN EN 61000-6-2 VDE 0839-6-2:2006-03 (EMI immunity)

The transistor controller's conformity to the mentioned standards does not concern the complete system. An extra EMC-test would be necessary to get the conformity for the complete system.

If the transistor controller is integrated in a machine, the machine must comply with regulation 2006/42/EG (machines directive). If not operating is not allowed.

If the supply voltage of a machine is > 50V AC respectively 75V DC, the regulation 2014/35/EC (low voltage directive) is to be observed.
