CAUTION
• If you conduct an open-close check for “Output contact 4”, Error 1 or Error 2 will occur.
This is because the built-in heater power of the detector, which is connected to “Output contact
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 10.6, “Reset”, later in this
manual).
