Operatingandfunctions
The preset flow rate is ignored if there is a running check for the correct behaviour of the outputs (see
chap. “8.7.3”).
This function makes it possible, like the Hold mode, to freeze the flow rate maesure, but to a preset value set by
the user.
When the digital input is activated:
• the device status LED flashes.
• the current transmitted on the 4-20 mA is frozen to the preset value of the flow rate.
• the displayed flow rate is frozen to the preset value of the flow rate.
• each transistor or relay output behaves depending on the preset flow rate.
• the totalizers do not increment any more.
• the preset flow rate is active until the digital input switches again.
