80
Output Time Limit
Enter the maximum amount of time that the relay can be continuously activated. Once
the time limit is reached, the relay will deactivate until the Reset Output Timeout menu
is entered.
Reset Output Timeout
Enter this menu to clear an Output Timeout alarm and allow the relay to control the
process again.
Name
The name used to identify the relay may be changed.
Mode
Select the desired control mode for the output.
Several standard settings that are available for most control modes are not available for Lag outputs. These features
affect the entire Lead Lag group and can be specified only within the Lead output’s settings. The settings for these
fields are propagated down through the entire Lead Lag group when changed for the Lead output. Although the
settings for these fields are identical for all outputs in the Lead Lag group, the handling by each Lag output may be
independent or group-managed.
Below are the settings that are in the Lead Relay settings that will affect the Lead Lag group:
Interlock Channels
Select the relays and digital inputs that will interlock this relay and all others in the
group.
Min Relay Cycle
Enter the number of seconds that will be minimum amount of time that each relay in
the group will be in the active or inactive state.
Normally this will be set to 0, but if using a motorized ball valve that takes time to
open and close, set this high enough that the valve has time to complete its movement.
Hand Time Limit
Enter the amount of time that each relay in the group will activate for when it is in
Hand mode.
Hand Output
This menu only appears for pulse relay or analog output Lead outputs.
Enter the output % desired for each output in the group when the output is in Hand
mode.
Off Mode Output
This menu only appears for analog output Lead outputs.Enter the output mA value de-
sired for each output in the group when the output is in Off mode, or being Interlocked,
or during a calibration of the sensor being used as an input. The acceptable range is 0 to
21 mA.
Error Output
This menu only appears for analog output Lead outputs.Enter the output mA desired for
each output in the group when the sensor is not giving the controller a valid signal. The
acceptable range is 0 to 21 mA.
The
Activate With Channels
setting, normally available for all outputs, is
not
propagated through the Lead Lag
group. This field can be entered independently for each Lag Output when the control mode of the Lead output is
Manual and the activation mode is Switch Based.
Most other settings for the various types of Lead control modes are managed independently from other outputs
within a Lead Lag group. In most cases, no
Activation Mode
settings are available, so the Lead output determines
the status for the entire group based on its settings and the current controller parameters. However, when an Activa-
tion Mode is enabled, the handling of some settings may require some additional explanation. For example,
• Duty Cycle - If a Lead output with a control mode of On/Off or Dual Setpoint has a Duty Cycle setting of less
that 100%, this cycle will be managed for the Lead output only. The Duty Cycle will drive other Lag out-
puts for Backup or Wear Leveling purposes. However, if additional Lag Output(s) are energized due to Set-
point-Based or Time-Based Activation Mode settings, the additional outputs will operate independently of the
Duty Cycle setting. The Lead output will continue to cycle On and Off, however, the additional outputs will
remain activated with 100% duty cycle until the setpoint deadband is satisfied.
• On Delay / Off Delay - If the Lead output with a control mode of On/Off, Dual Setpoint, or Manual has either
an On or Off Delay Time setting specified, the delay will be managed for the Lead output only. If one or more
Lag outputs provide Backup or Wear Leveling support, the Delay Times would also effect these outputs.
However, if additional Lag Output(s) are energized due to Activation Mode settings, the additional outputs will
