DOL 100 Water 8l/16l Box
Technical User Guide 5
1 Product description
The DOL 100 Water 8l/16l box is used for measuring the water level to ensure that the water pressure is in or-
der. The DOL 100 will promptly show faults in the water supply, e.g. clogged or broken water pipes or lacking
water supply.
DOL 100 transforms a signal from the water level sensor into digital signals and transmits them to the controller
using CAN bus communication.
• DA 100 Water is available in two variants:
• Connect up to 8 water level sensors to the DOL 100 Water 8I box.
• Connect up to 16 water level sensors to the DOL 100 Water 16I box.

3.2 Assembly
3.2.1 DOL 100 Water box
Mount DOL 100 Water box on the wall using four screws.
3.2.2 Water level sensor
Normal
water level
Drill two holes in the water pipe with a 2.4 mm drill when
the water level is normal.
The distance between the holes should be 20–40 mm.
Unscrew the two studs in the water pipe.
Make sure not to tear the thread.
Install the wire including cable clips on the stud with screw
and star washer; retain the pole when you tighten the
screw.

4 Installation guide
4.1 Electrical connection
Installation, servicing and troubleshooting of all electrical equipment must be carried out by quali-
fied personnel in compliance with the applicable national and international standard EN 60204-1
and any other EU standards that are applicable in Europe.
The installation of a power supply isolator is required for each motor and power supply to facilitate
voltage-free work on the electrical equipment. SKOV does not supply the power supply isolator.
4.2 Cable routing
To prevent water from running into the DOL 100 via cables
and screwed connections, run the cables so that water does
not gather around the cable in the gasket of the screwed
connection.

The DOL 100 must have a specific CAN ID for the controller to communicate with it.
The address of the individual DOL 100 corresponds to the address in the controller in
the menu Technical | Setup | Installation | I/O Modules | Additional I/O Modules
Address switches X10 is set to 5 in connection with DOL 100 water and 3 in con-
nection with DOL 100 digital.
The address switches X01 are set to the displayed number or letter after the fig-
ure 5 or 3 in the controller.
If change of address, restart DOL 100 for the change to take effect.
(D) TERM ON
Jumper is set to (ON).
(E) TERM ON CAN bus termination. If DOL 100 is the last node in the CAN bus communication, the
jumper must be set to (ON) .

6 Troubleshooting Guide
Error
No light LED on the CAN bus
coupler.
Check the 24 V DC power supply to the DOL 100.
Check that you have installed the DOL 100 water 8I/16I box and water
level sensor in the controller, see section Setting up the DOL 100 in the
controller [}14]
No CAN bus communication con-
nectivity with the DOL 100 water
8l/16l box.
Check resistance between CAN H and CAN L; the resistance must be
approximately 60 ohms.
If the resistance is > 100 ohms, a termination is missing.
If the resistance is < 45 ohms, there are too many terminations.
