6.8.6.2 Output current configuration
This menu allows you to switch the format of the output current between 4-20 mA and 0-22 mA
.
Factory setting: the output current is 4-20 mA
6.8.7 [INH]ibition submenu
Maintenance inhibition can be configured in « frozen » mode (factory setting) or « free » mode.
•
In « frozen» mode, the outputs (current and relay) remain in their previous state.
•
For example, if the device displays a fault (2.0 mA), it will remain in this mode during the
inhibition.
•
If the device is configured in « free » mode, the current output will remain at the same level
than the permanent inhibition
