Operation of Devices without Displays
5.1
Preparation
This unit can be programmed before or after installation.
• Connect an ampere meter to the device's output (between terminals I and L+).
• Note that after each action, a brief oscillation/deflection of 20 mA occurs (verifica-
tion of a successful action).
The following functions can be programmed without a display unit:
• Zero point adjustment with a full or empty container (with/without pressure)
• Span adjustment with a full or empty container (with/without pressure)
• Integration time
• Reset to manufacturer's defaults
An error signal is caused by a current surge (21 mA or 3.6 mA; 5 sec) when
the zero point or span setting fall outside of the sensor's nominal pressure
range during adjustments with existing pressure. No values are stored.
The keypad becomes inactive after 10 min. of disuse. All settings will de-
fault to previously stored values. Only settings that have been confirmed
with the "OK" function are stored.
