6.8 Testing digital/analog outputs
The digital/analog outputs are tested under menu item “IO Test”.
Signal test “IO test”
The following signals can be set and/or tested:
Analog outputs: Assignment of the analog outputs is preconfigured but can be changed
manually, see “Assigning analog outputs “AO Mapping””, page 82.
Factory setting:
● AO1 = K-value
● AO2 = NO
● AO3 = CO
● AO4 = temperature
Relays
● Relay for device malfunction (“Fault”)
● Relay for maintenance request (“Maintenance Req.”)
6.8.1 Testing the analog output AO1
Fig. 72: Setting and checking the rated current for AO1
▸ Pressing the “Set” button outputs the value at the analog output.
▸ It is now possible to check at the analog output or in the control station whether 4mA is
output on AO1 (factory setting K-value).
NOTE: The maintenance signal must have been activated to test the digital
and analog outputs and to set the values.
▸ Set the maintenance signal in the menu, see “Activating Maintenance mode”,
page 74 or
▸ password prompt before setting the value, see “Switching the maintenance signal
on/off”, page 74.
If the password is set to enable a function, all further settings can be changed within 30
minutes without having to enter the password again.

Submenu item “Filter” is required in connection with the test tool and is described in the
Section “Maintenance”, see “Visibility test with VIS test tool”, page 89.
The rated current set on the analog output can be reset using “Maint” -> “inactive”. The
VISIC100SF switches back automatically to measuring mode after 30 minutes, see
“Activating the setting range via menu item “Maint””, page 53.
