Installing The Terminals - Quick CHC1103 Manuel D'installation

INSTALLING THE TERMINALS

In order for data to be correctly transmitted when several chain counters are employed,
terminator (120 ohm) must be installed.
The terminator should be connected between signals CANH and CANL of the first and last
chain counter included in the network, as illustrated in the figure below:
Example of CAN connection with more CHC instruments
• the first A CHC1203 is equipped with internal termination;
• the second B CHC1203 NT does not feature any termination;
• the first C CHC1103 is equipped with external termination.

CHAIN COUNTER CALIBRATION
Before using the chain counter, either the manual or automatic calibration procedure has to be effected.
The calibration procedure consists of setting the following data: unit of measurement used by the chain counter, lenght of
chain unwound each gypsy lap and number of magnets installed on the gypsy.
To calibrate, go to menu CALIBRATION or AUTO CALIBRATE (see chapter SETTING THE CHAIN COUNTER).
Multiple chain counters
The chain counter is equipped with a CAN BUS data interface that allows several chain counters to be connected and
information to be exchanged (CAN network).
A MASTER/SLAVE network structure is used, i.e. there is only one main chain counter (MASTER) and all the other chain
counters are secondary (SLAVE).
The network must have at least one MASTER chain counter.
If there is more than one chain counter, instrument CHC1103 must be set as SLAVE. The instrument CHC1103 should be
set as MASTER only if it is the only instrument present.
The task of the MASTER chain counter is to align the length of the chain lowered and the operating parameters of all the
SLAVE chain counters.
The MASTER therefore is used as a reference for all the other SLAVE chain counters.
If a parameter in a menu for a SLAVE chain counter is modified, the change is actually made to the MASTER chain counter
that will automatically update all the SLAVE chain counters (except for menu PERSONAL SET, UTILITY and CAN CONFIG
that cointain particular functions and parameters for every single chain counter not shared in network with the other
chain counters).
The MASTER chain counter should be on even if the commands to the windlass are transmitted from SLAVE chain
counters or other windlass operation switches.
If the MASTER chain counter should malfunction, one of the SLAVE chain counters can be set up as the MASTER.
Before using the chain counters on the CAN network, make sure the MASTER and SLAVE settings of all the chain
counters are correct and that the network works in a trouble-free manner.
