DESCRIPTION OF SIGNS
LC5296-AT LC5296V-AT, and LC5248E-AT can be configured as PID or ON-OFF
Controller.
To change configuration, following steps are required to follow.
From menu parameter settings if user enter 5296 Password in Pass menu in
configuration menu then it will displays
1. In conf menu, pass sub menu, if user enter ‘5296’, sub menu will come
COP: it has two options PID or ONOF.
2. Selected COP in above menu will be displayed on power on condition.
Like PV: 5296 SV: TC-E then PV: COP SV: ONOF. If COP: PID is selected
then PV: COP SV: PID.
3. For COP = PID, then in conf. mode, after OT menu, COP menu will come.
With three option, P, PI or PID.
On selection of PID / ON-OFF, only relevant parameters will be displayed in menu.
