FUNCTIONAL CHECKS
A =
Measure EXCITATION voltage at transducer terminals.
B =
Check function of ZERO control while monitoring output signal for 0v.
C =
Adjust EXCITATION voltage control for specified voltage. Refer to transducer CAL.
SHEET for correct voltage.
D =
Connect transducer SIGNAL terminals together and repeat B.
E =
Check the transducer is correctly wired.
F =
Check that SUPPLY and OUTPUT circuits are wired correctly and not
simultaneously grounded if using SINGLE SUPPLY.
G =
Disconnect transducer and repeat D.
H = Check that if D works, the transducer is zero when attempting to obtain ZERO o/p.
J =
Check EXCITATION setting with the transducer disconnected.
K =
Try another transducer if possible, otherwise return transducer to factory.
L =
Try another S7DC if possible, otherwise return S7DC to factory.
