Adjustments
Before our product is dispatched from our factory, input signal against supply pressure or supply
pressure against input signal will be set correctly. But, if additional setting requires, please see below.
6.1
Zero and Span Adjustments of Output pressure
(Based on 4~20mA / 0.02~0.1 MPa)
1)
After wirings have been completed, please supply 4mA as input signal to YT-930. Please check
output pressure and adjust zero adjustment bolt by using small (-) screw driver. In general, zero
should be set at 0.02 MPa
2)
Supply 20mA. Please check output pressure and adjust span adjustment bolt to required end
output. In general, span should be set at 0.1 MPa.
3)
Supply 4mA again. Please check the output pressure and repeat step 1 and 2 until required point
have been set completely.
4)
Close the cover base completely
6.2
Zero and Span Adjustments of Feedback Signal
(Based on 4~20mA / 0.02~0.1 MPa)
1)
Feedback signal requires DC 9~28V. Supply 4mA. Please check if the output pressure is at zero
point and receive feedback signal correctly. If not, adjust zero adjustment bolt by using small (-)
screw driver until the receiving feedback signal is set as 4mA.
2)
Supply 20mA. Please check if the output pressure is at end point and receive feedback signal
correctly. If not, adjust span adjustment bolt by using small (-) screw driver until the receiving
feedback signal is set as 20mA
3)
Supply 4mA again. Please check the feedback signal and repeat step 1 and 2 until required point
have been set completely.
4)
Close the cover base completely before using the product.
