12LS Controller Installation and Operation Manual, Rev 3 ... - Watlow

Guided Menus Simplify SetupThe ANAFAZE 12LS directs operator and supervisor changes with guided menus. Two levels areprovided: one for operator changes and one for supervisor controller setup.Operator Changes: Single dedicated keys are used to make process changes from thesingle loop display. The setpoint can be changed, the loop can be set to auto or manual,and ramp and soak loops can be started, held, or stopped. If the loop is set to manual, thepercent output can be changed. These changes can be locked out from the supervisormenus if desired.Supervisor Setup: Detailed editing is done by pressing a special sequence of keys to enterthe setup menus. The supervisor is guided through a list of functions to change:Global? This is used to save and restore jobs, define action on power up,communications address and baud rate, communications error checking, panel lock,and alarm delay.Inputs? Input sensor type, engineering units, scaling, and sample time for pulseinputs.Control? The loop control constants including: Proportional gain [P], Integral orreset [I], and derivative or rate [D], and a digital output filter. For the dual outputs,a second gain, reset, rate, filter and spread can be entered for the second output.Output? Selects the control output including: analog, on/off, cycle timeproportioning, distributed zero crossing, and reverse [heat] or direct [cool] action.The heat output can be directed to the terminals or ribbon connector.Alarms? Independent deviation alarm band, high process, and low process alarmscan be set for each loop. Each alarm can be set to activate any of the digital outputson alarm. A deadband can be entered for each loop.Ramp/Soak? If this option is installed up to eight, 20 segment ramp and soakprofiles can be defined.I/O Test? This is used to check the state of the digital inputs and outputs.1-3
