8.4.7 Auxiliary contacts 1 {14070} and 2 {14122}
When connected to the ARM-02 module (see chap. 9.3 – p. 42), the solar charge controller
VarioString has two additional external auxiliary relays with potential-free dry reversing contacts.
These two relays make it possible to realize multiple functions with appropriate cabling and simple
programming.
The programming of each
contact is
independently. The auxiliary
contacts are activated and
deactivated with a 2 second
delay to avoid too frequent
switching.
The auxiliary contacts react
to different types of signals,
graphically illustrated below.
Basic events that activate
the contacts are:
 Simple events
 Scheduled events
 Levels
In the following descriptions,
each parameter has two
reference numbers.
reference number on the left
refers to the auxiliary contact
1 and the reference number
on the right refers to the
auxiliary contact
({reference auxiliary contact 1} {reference auxiliary contact 2}).
8.4.7.1 Operating mode {14071} {14123} (automatic)
The auxiliary contact can be controlled in 4 different ways:
Manual ON: in this mode, the contact is permanently activated "ON" whatever the external
conditions or programming.
Manual OFF: in this mode, the contact is permanently deactivated "OFF" whatever the external
conditions or programming.
Automatic: in this mode the auxiliary contact is activated according to the conditions and restrictions
of its programming.
Reversed automatic: in this mode, the conditions and restrictions define the deactivation of the relay.
8.4.7.2 Combination of the events for the auxiliary contact {14072} {14124} (first active (OR))
This parameter defines how various events intended to activate the auxiliary contact are combined.
The contact can be activated either by a single event (OR function) or by all events being fulfilled
at the same time (AND function).
8.4.7.3 Contacts activated by an event {14077} {14129}
Different states and events within the installation can be used to activate the auxiliary contacts. The
events can be combined with each other to create complex functions.
