1 Technical safety information
1. Commissioning and operation of the device may only be performed by qualified
personnel. "Qualified personnel" as defined by this technical safety information
means persons who have the authorisation to start up, earth and designate devices,
systems and electric circuits in accordance with security technology standards.
2. Mounting, positioning and wiring may only be conducted when the electricity
supply to the assembly has been cut off.
3. The faultless and safe operation of the product presupposes proper transport,
appropriate storage, positioning and assembly, as well as careful operation and
maintenance.
4. Voltage must only be supplied by VDE-tested and CE-certified power packs.
5. Ensure that the voltage supply and the data cable are correctly connected.
6. If the product is brought into the working area from a cold environment,
condensation may form. The product must be completely dry before being
commissioned. Do not assemble or install the product near water or in damp
surroundings.
7. Do not take the product apart or remove the enclosure. The guarantee rights will
become invalid if the housing is opened.

2 Function of the CAN bus Repeater
The CAN bus repeater extends the CAN bus within the E*LDS system by a further 500 m, see the operating
instruction introductory chapter in the E*LDS documentation), see operating instruction „E*LDS for
systematic cooling - Basics and general safety and connection instructions“ of the der E*LDS documentation.
In this process, CAN bus data from the first (primary) CAN bus segment is transformed in a second
(secondary) CAN bus segment. In order to implement the CAN bus protocol from the primary side on the
secondary side, and the reverse, the CAN bus repeater is equipped with its own microcontroller.
Note: The determination „First CAN bus segment“ resp. „Second CAN bus segment “ is scalable.
CAN bus Repeater (order No. KGLZCANREP)
Interfaces
2 x CAN bus in accordance with ISO/DIS 11 898
Voltage supply
The CAN bus repeater is powered by an external 24 V DC power pack, order No. KGLNT24V1P.
A maximum of 2 CAN bus repeaters can be employed in an E*LDS system, for
further details see the introductory chapter in the E*LDS documentation.

3 Installation and Commissioning of the CAN Bus Repeater
3.1 Installation and connection to the CAN bus
Before commissioning, the CAN bus repeater must first be connected to the first CAN bus segment via the
front COMBICON plug. The second CAN Bus segment is then connected to the top connections of the CAN
bus repeater. Finally, the device is supplied with 24 V DC power (power pack, order number KGLNT24V1P):
Example:
Picture 3.1: Connection of the CAN bus-repeater
Note: The determination „First CAN bus segment“ bzw. „Second CAN bus segment “ is scalable.
* The start and end of a CAN Bus segment must each be connected to a terminating
resistor R=100 Ohm (0.25 W)!
Tip: Use connector set with terminating resistor to terminate the CAN bus,
order No. KGLCANTERM.

CAN bus cable type: LiYCY 2x2x0,75 mm“ – twisted pair,
see the introductory chapter in the E*LDS documentation.
Details for the connection to the CAN bus are contained in the introductory chapter
of the E*LDS documentation (e.g. specification of the cable type, permissible cable
length, required terminating resistor, the correct routing and the max. number of
CAN bus repeaters).
Incorrect shielding can lead to electromagnetic noise fields.
During wiring it must be ensured that the cables with shielding are correctly
connected.

3.3 Commissioning
The commissioning of the CAN bus repeater consists of the following steps:
1. Connect the CAN bus repeater to the first and second CAN bus circuits, see chapter 3.
2. Attach the CAN bus repeater to the power supply 24 V DC.
3.4 Indication of the Operating Status
The CAN bus repeater is equipped with a display element consisting of a yellow and a green LED with the
following functions:
•Yellow LED (BA) = CAN bus status
Flickering yellow LED:
The CAN bus repeater is transmitting data via the first (primary) CAN bus segment.
•Green LED (ON) = operating voltage
Flickering green LED:
The CAN bus repeater is transmitting data via the second (secondary) CAN bus segment.
•Both LEDs are flashing at 0.5 second intervals:
The processor is running, no data is being transmitted via the CAN bus.
•Both LEDS are extinguished:
- No 24 V DC voltage supply or
- CAN bus OFF: The device is receiving data but is not able to re-transmit it.
