viewing of configuration menus.
TECHNICIANS MENU GROUP
The TECHNICIANS MENU group consists of the XMITTER CONFIG menu and TECHNICAL PAGE menu. These
menus contain items that are typically factory configured depending upon the type sensor and input
connected. Care should be used when modifying these variables as some items will prevent proper
operation and could endanger personnel.
Access requires a special key sequence of four UP keystrokes to prevent accidental modification of critical
items.
XMITTER CONFIG MENU
The XMITTER CONFIG menu is used to activate channels, precisely calibrate 4-20mA outputs and set time
/ date. To access the XMITTER CONFIG menu, press and hold the NEXT key for 5-seconds until the screen
appears requesting the special key sequence.
WARNING
: TARGET GAS MONITORING AND ALARM PROCESSING ARE NOT ACTIVE WHILE IN THIS MENU.
