CAUTION
If you conduct an open-close check for the contact output 2, Error 1 (cell voltage failure) or Error
2 (heater temperature abnormal) will occur. This is because the built-in heater power of the
detector, which is connected to contact output 2, is turned off during the above check. So, if the
above error occurs, reset the equipment or turn the power off and then back on to restart (refer to
Section 10.4, “Reset,” later in this manual).
7.10.2 Checking Calibration Contact Output
The calibration contacts are used for the solenoid valve drive signals for the Automatic
Calibration Unit. This output signal enables you to check the equipment operation. Check the
owmeter gas ow for that operation.
Follow the steps in Table 7.12. The table uses an example with a zero gas solenoid valve.
