1.4.2.6 Control Output (Voltage pulse Output, Electric Present Output) and Wiring Transmission Output
▶ Turn off TEMP880S mainframe power and external power supply when wiring the control
output (SSR, SCR) and transmission output due to danger of electric shocks.
▶ Be careful with output polarity. Incorrect connection causes damage to the mainframe.
▶ Use output wire that has shield attached. Shield should be done as 1point ground
▶connection.
