Parameterization of the safety module

51 / 112
Test pulses
Shutdown time
(INTERBUS-Safety only)
This parameter is only available in an INTERBUS-Safety system.
The shutdown time is calculated from the “Switch-off time” and “Value range of switch-off
time” parameters.
Shutdown time = “Switch-off time” x “Value range of switch-off time”
Example:
Shutdown time = 20 x 10 ms = 200 ms
Parameterize the lowest possible value for the shutdown time according to your application
in order to ensure short response times.
Value range of switch-off
delay for stop category 1
Value x 10 in ms
Value x 100 in ms
Value in s
Value x 10 in s
Value range / Unit for the parameterization of the “Switch-off delay
for stop category 1” parameter.
Please observe the notes below this table.
Enable Disabled
Enabled
Disabled (default value): the corresponding safe output is oper-
ated exclusively according to the safety logic.
Enabled: Enable is active; the safe output data is output after
being ANDed with the standard output data of the standard con-
trol system.
See also Section “SafetyBridge” on page 29.
Test pulses (output dis-
abled) (in software: test im-
pulses (output switched
off))
Disabled
Enabled
Enabling and disabling of test pulses. For these test pulses, the
output drivers that are disabled are temporarily enabled for test
purposes.
See note below this table.

Note on test pulses
If the test pulses are disabled, cross circuits and short circuits cannot be detected.
Regardless of the parameterization selected under “Test impulses (output switched off)”,
the outputs parameterized as “Not used” are tested by test pulses.
Please also refer to “Requirements for controlled devices/actuators” on page 21 and Sec-
tion “Connection examples for safe outputs” on page 55.
Value of shutdown time 20
“Value range of shutdown time” Value x 10 in ms
For an example of calculating the minimum parameterizable shutdown time for your ap-
plication, please refer to the UM EN INTERBUS-SAFETY SYS user manual.
If the shutdown time is parameterized with a value less than 15 ms, this value is rejected
as a parameterization error (error code 021x
hex
).
