When the LED display of an ITV series electro-pneumatic regulator indicates an error, what are the next steps to be taken? At present, Er. 1 (Error 1) is displayed on an ITV2030-222S electro-pneumatic regulator.

For the current/voltage type, 10-bit digital input, and 16-point preset input type ITV1000/2000/3000 series electro-pneumatic regulator, the error contents are indicated in the operation manual.
Refer to the ITV standard type (refreshed product) operation manual. Although this product is a 0 to 5 VDC input signal type, error 1 occurs when an input signal exceeding 5 V is supplied.
Check the signal and return it to within the rated range. Turn the power OFF and then ON again. The ITV series operation manual can be found here.
