Analogue inputs
Press the name of an analogue input to change it.
"min" is used to select the minimum sensor value.
Selecting "min"=
- "-1" automatically sets the pressure unit [bar]
- "-14.5" will automatically set the pressure unit [psi]
- "0" can select the units bar / psi / kg / lbs.
"max" is used to select the maximum sensor value.
If there are inputs that are configured as weight (kg or lbs), the "Tare setting" menu is used to automatically add an input field for the tare weight value.
The current values of the analogue inputs are displayed as soon as the unit and the measuring range are entered.
Pressing "Next" will take you to the analogue alarm configuration.
Up to 8 alarms can be configured here. In the first column, all analogue inputs are automatically numbered. Pressing one number scrolls to the next analogue input which means that multiple alarm configurations can be assigned to one input, for example.
The analogue inputs that are to trigger an alarm must be switched from OFF to ON. The conditions for alarm triggering and the alarm designations displayed when activated can then be set. A single analogue input can be assigned to multiple alarm actions. For example, it is possible to set high and low pressure alarms on a single pressure transmitter.
Pressing "Next" will then open the list of alarm names. You can assign different alarm actions to these alarm names.
Press "No action" to scroll to the required alarm action.
These are the possible settings for alarm actions:
Action | Description |
No action | The alarm is not active |
Warning | The alarm is active but does not switch any valves |
Shutdown | The alarm is active and closes all corresponding valves |
1LS-U | The channel is active and an alarm is triggered on the 1st changeover system on the left-hand side. The gas source is changed over from the left to the right-hand side in this process. |
1RS-U | The channel is active and an alarm is triggered on the 1st changeover system on the right-hand side. The gas source is changed over from the right to the left-hand side in this process. |
2LS-U | The channel is active and an alarm is triggered on the 2nd changeover system on the left-hand side. The gas source is changed over from the left to the right-hand side in this process. |
2RS-U | The channel is active and an alarm is triggered on the 2nd changeover system on the right-hand side. The gas source is changed over from the right to the left-hand side in this process. |
On the next screen, the settings have been configured to switch the 1st system from the left side (1LS-U) to the right side if the cylinder pressure is too low.
A changeover of the 1st system from the right side (1RS-U) to the left side if the cylinder pressure is too low has also been configured.
If the pressure drops to 10 bar, a pre-alarm is issued in the form of a warning.
If the outlet pressure is too high (20 bar), valves 1 and 2 are closed (shut off).
For the shut-off of the valves, designations V1 and V2 must be pressed.
