Configuration / parametrisation of master-slave defrost via CAN bus
The controllers must be configured so that defrosting can take place. In the case of the master, a defrost is
initiated via the internal clock, the external contact or via manual defrost (CAN / local). The master, with respect
to the parameter “
M/S Abt Fkt
” must be set to
“Master”
(menus 2-2-1 and 2-2-2). The parameter “
M/S CAN Adr.
”
is of no relevance for the master.
The slaves, with respect to the parameter “
M/S Abt Fkt
” are set to “
Slave
”. The parameter "
M/S CAN
Adr.
"
must
be set to the CAN address of the master controller, and for all participating slave controllers.
Special application case - Synchronisation of both defrost zones
If the M/S CAN address on a slave is set to "--", a defrost via internal and external defrost timers is possible.
This enables both zones of the respective controller to be synchronised so that they return to cooling
simultaneously following the defrost.
Quick Start Guide
Set which controllers should defrost or switch to cooling together. Define one of the controllers as the defrost
master.
Configure the defrost master (e.g. controller with CAN address 11) as follows: under 2 Setpoints - 2 Defrost
- 1 Zone 1 :
1. Set M/S Abt. Fkt to “Master” and
2 M/S CAN Adr. to “–“
Configure all slaves as follows: under 2 Setpoints – 2 Defrost – 1 Zone 1:
1. Set M/S Abt. Fkt to “Slave” and
2. Input M/S CAN Adr. (CAN address of the master (e.g. 11))
Configure the defrost on the master,
1. safe defrost time and defrost times or external defrost in menu 3 Clock - 2 defrost timer (note: during
master / slave operation, the controller always reacts to the external defrost timer even if defrost timer has
been set to INT)..
2. defrost termination temperature, wait time and drip time for zones 1 and 2 in the menus 2-2-1 and 2-2-2
(note: the slaves adopt the wait time and the drip time from the corresponding zones of the master. If the
master should operate in single-zone mode, a slave in two-zone mode adopts the wait time and drip time
from zone 1 of the master for for both zones).
Check whether the sensor for the defrost termination temperature (R1.x) is connected and is supplying
plausible values.
It is recommended to set the parameter “
M/S CAN Adr.
” on the master to “—“.
