NOTE
• If you conduct an open-close check for contact output 4, Error 1 or Error 2 will occur.
This is because the built-in heater power of the detector, which is connected to contact
output 4, 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).
