7.7.2
Define Operating or Standby Mode
Each output may be defined as Operating (OP), Standby (ST), or Not
Used (NU). This setting takes precedence over any setting in the over-
ride menu (see 7.12 - Override Output). The default settings are:
• Outputs 1 and 2 are in Operating (OP) mode
• Outputs 3 and 4 are in Standby (ST) mode
• Outputs 5 through 8 are in Not Used (NU)
To change the mode:
• From the Setup Outputs Menu, shown at right, use the arrows
to choose Mode for the selected output and press Enter .
• To change the output's mode, use the arrows
these options:
• OP (Operating)
• ST (Standby)
• NU (Not Used)
• Press Enter .
7.7.3
Enable or Disable an Output Device in Alarm Status
You may choose whether to Enable or Disable an output when the con-
nected device is in alarm status. The default setting for all output
points is Enabled. If Enabled, the device stays enabled when in alarm
status. If Disabled, the device is disabled when it goes into alarm.
• From the Setup Outputs Menu, choose In Alarm, as shown at
right, and press Enter .
• To make a change, use the arrows
to determine what happens when an alarm is detected in the
device.
• Press Enter .
7.7.4
Enable or Disable a Device during Emergency Power Operation
You may choose whether to Enable or Disable an output when the AC8
is in emergency power operation. The default setting for all output
points is Enabled.
• From the Setup Outputs Menu, choose Emerg Op, as shown at
right, and press Enter .
• To make a change, use the arrows
to specify what occurs in emergency power operation.
• Press Enter .
7.7.5
Configure Output for Loss of Power ("Fail-Safe")
Each output has an associated jumper that can help prevent undesired
effects when the controller board loses power. For example, without the
proper fail-safe jumper setting, a loss of power might close a switch that is Normally Open (NO)—per-
haps shutting off an environmental unit or a fan or closing a valve.
This fail-safe jumper setting is unrelated to configuring an output as Normally Open (NO) or Nor-
mally Closed (NC), as described in 7.7.1 - Define Output as Normally Open or Normally Closed.
To configure a digital output jumper for a loss of power:
• Set the jumper in the "OFF" position (factory default) to make the output Normally Open (NO).
• Set the jumper in the "ON" position to make the output Normally Closed (NC).
For more information, see 3.2.3 - Setting the Digital Output Jumpers.
