REDUNDANCY
The equipment can usually interface with the Peak CANBUS redundancy system for 1:1, 1:2
and 1:N redundancy systems, please check with the factory for specific options/availability.
1 Identifier -
The identifier for each converter can be either [A] or [B] in a 1+1 redundant
system or [A], [B] or [STANDBY] in a 2+1 system.
2 Priority -
The priority of an individual converter in a redundancy system can be set via this
option. The converter with the higher priority will command the standby if it alarms.
Note: Priority is not applicable [N/A] in a 1+1 redundancy system.
3 Type -
The type of redundancy system that the converter is part of, is set by pressing 3 and
scrolling through 1:1, 1:2 and 1:n
4 Change Over -
This sets the converter to be either an online unit or offline (standby) unit, this
is only applicable in 1:1 and 1:2 redundancy setups, and when the unit is in manual mode.
5 Mode -
This sets the 1:1 and 1:2 redundancy to be manual or automatic.
6 System -
This brings up the following screen:
1 System Number -
This allows the user to select which system the units are attached to. This
allows different redundancy controllers and their associated units to all use the same
redundancy cable. In normal operation this should be 0, however if the redundancy system is
part of a UPC system then this system number should be something other than 0. All units
attached to the same redundancy controller should have the same system number, and it
should be unique from any other redundancy controllers attached. This is a new addition in
version 2.28 software and newer, all older units are essentially on system 0 permanently.
2 List units in system -
This displays a menu screen showing the other units that can be seen
on the same system as this unit.
1 for 1 Redundancy
For 1:1 switched redundant operation a pair of units is required along with typically an
R1000HH external switch unit for receiver units, or a T1000HH external switch unit for
transmitter units.
In use, the redundancy type on the configure/ redundancy menu is set to 1:1 and one unit is set
to identifier “A” and the other to identifier “B”. The switch unit is connected to the rear panel 9
way connector with the supplied cables and the units will self detect and set one unit to online
and the other will be set to standby. A changeover will be caused by an alarm detected in the
online unit or changeover (keypad 4) being selected, this will result in the configuration of the
