8. Press Mode/Enter .
Set switching limits
Follow these steps to set the limits that cause the outputs to switch.
Procedure
1. Select SP1 or SP2 from the menu.
2. Press and hold Set to modify the parameter value.
3. Set the limit at which the output switches.
4. Press
Mode/Enter
.
5. Select rP1 or rP2 from the menu.
6. Press and hold Set to modify the parameter value.
7. Set the limit at which the output resets.
The rPx value is always lower than SPx. The pressure transmitter accepts only values
lower than the value for SPx.
8. Press
Mode/Enter
.
Automatically scale the analog output
Follow these steps to set the start and end value of the analog output to the current
system pressure reading. If the automatic setting is invalid, the pressure transmitter
displays UL or OL. After acknowledging an incorrect value, the pressure senor displays Err
and does not accept the incorrect value.
Procedure
1. Set the minimum pressure requested in the system.
a) Select tASP from the menu.
b) Press and hold Set .
The display flashes the current set value.
c) Release Set when the value stops flashing.
The pressure transmitter displays the new value.
d) Press Mode/Enter .
The current system pressure is defined as the start value for the analog
signal.
2. Set the maximum pressure requested in the system.
a) Select tAEP from the menu.
