User guide

◎ Before connecting sensors, check driving voltage and output signal type of the sensor.
Since output signal types of the sensors are divided into Open Collector and Voltage
Output type in general, the cabling must be done properly after considering these
typed.
◎ If you want to use Alarm Input, the types of sensor must be selected in OSD menu
. The sensor types are Normal Open and Normal. If sensor type is not selected properly,
the alarm can be activated reversely.
◎ Maximum allowable electrical load of relay is shown bellow table.
