Chapter 2: Pre-Installation Planning
• For a 6 Slot Expansion Box => use two 3 Slot Expansion Boxes.
• Use an Expansion Box with an external power supply of 150 Watts wired on the Safety Network.
Use Dual links on (Automation | Safety).
Failsafe Plug-in Modules
You can purchase Failsafe Plug-In Modules that relay output contacts if the relay coil is de-energized in
the event and Failsafe Mode of a power outage.
NOTE: Failsafe Plug-In Modules enter into a Failsafe Mode when powered down.
Backup Mode and Failsafe Operation
The EDGE system enters backup mode when communication is lost between the EDGE 2 controllers and
Expansion Boxes. Once in backup mode, the plug-in modules take over operation of the equipment con-
nected to them. A plug-in module only operate the equipment wired to it, and not equipment on other
plug-in cards. When using the EDGE for backup or failsafe operations, there are certain rules you must
follow when wiring your equipment.
Wiring for backup operations requiring temperature, static pressure, or relative humidity measurements
can be done through the 8I/4V/6R F,16I/6R F, 4I/8REL F, and 4I-6R-2LD F modules. To ensure proper
operation of equipment in the event of a EDGE 2 controller malfunction, the following backup operations
(in priority order) are recommended:
• Minimum ventilation stage fan outputs
• Minimum ventilation stage inlets
• Intermediate temperature control stage fan outputs (stage 2-3)
• Heater
• Other inlets
• Other fans
• Brooders
• Cooling
• The fan outputs wanted in backup mode must be connected to a module with backup capabilities,
and with at least 1 inside temperature probe
• The inlet outputs and potentiometer feedback assigned to backup mode must be connected to a
module with backup capabilities, and with the corresponding inlet assigned probes
• The heater outputs wanted in backup mode must be connected to a module with backup capabil-
ities, and with the corresponding heater assigned probes
• The cooling outputs wanted in backup mode must be connected to a module with backup capabil-
ities, and with the corresponding cooling assigned temperature & RH probes
• It is recommended to connect static pressure sensors to the same plug-in module as the controlled
inlet machines on a board with backup capabilities to maintain static pressure control mode in
backup operation
• The inlet potentiometer must be connected to the same module as the inlet machine
