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).
