7.11.9.4 Output parameter menu
In this menu the input sources that switch the relay can be set. Setting options for
Source state are: Alarms A1 to A8, Error, Warning, Information, Inhibit, Comfail.
To configure an input source:
1. Select Output.
2. Select Logic type.
► Single
A channel is defined as an input source for a special state.
a. Select Source state. This sets the state of the input channel as condition for
b. Select Source channel. This sets a channel as input source.
c. Select channel and confirm.
► Common
All channels are defined as input source. The relay is switched if one of the
channels meets the condition.
a. Select Source state. This sets the state of the input channel as condition for
setting an Activation delay time of 0.5 s.
► Voting
The Voting defines the number of channels on which at least one of the defined
state conditions must be met to switch the relay.
a. Input the number of channels in which the condition must be met to switch
b. Select Source state. This sets the condition of the input channel.
Description
Set delay time for activation of the relay.
Example: The Activation delay time offers the option of
setting commonly controlled actuators (e.g. fan and duct) to
a defined time sequence. The fan can be controlled so it
only switches on if the duct has opened.
The delay time makes an output respond with a delay (con-
figured delay time) to a pending alarm condition. If the alarm
condition is no longer applicable during this period, there is
no alarm at the output.
This does not apply to relays configured as latching relays.
Dräger recommends leaving the parameter value at 0 (zero)
for safety-related applications.
Adjustable range: 0 to 6000 s; default setting 0 s

down control of a connected fan).
