The max. possible rate of increase of the gas concentration must be taken into
account when determining the delay time. Delay times must be taken into account
when determining the system response time and must essentially be kept as short
as possible. This applies for the measurement of:
– combustible gases and vapours
– oxygen
– toxic gases
This note does not relate to the Deactivation delay time.

8.5.5.4 Output parameter menu
In this menu the input sources that switch the relay can be set. The setting options
for Source state are: Alarm 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.

Description
Set behaviour of the relay.
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) in
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condition is no longer applicable during this period, there is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 for latching configured relays.
Dräger recommends leaving the parameter value at 0 (zero)
for safety-related applications.
Adjustable range: 0 to 6000 s; default setting: 0 s
Set the deactivation delay time of the relay (e.g. for run-
down control of a connected fan).
Adjustable range: 0 to 6000 s; default setting: 0 s
switching the relay.
