About LAG LEAD
The lead lag-sequencing controller shall be microprocessor based, menu driven site tunable unit that is preprogrammed for the specific functions delineated. The unit shall have a two-line Vacuum Fluorescent display with 20 alphanumeric characters per line. This display shall show all input variables, set points, status, alarm messages and prompts for on/off and timers. Operator interface shall be through a front panel alphanumeric keypad with 20 tactile-feedback buttons for entering configuration parameters and for scrolling between display screens.
The controller shall exhibit sequential logic as well as proportional and integral loop control capable of full modulating control as specified. CPU failure with auto boiler failure skip and manual transfer capability for modulating control shall be standard.
As a minimum the controller shall have 22K RAM or 52K EPROM with a 0.5 ms/K scan time and CMOS RAM with battery back up. The unit shall have as a minimum 11 optically isolated inputs including transmitted or digital inputs, with expansion if the application should require it. Modulating outputs signals to the final elements shall be 135 ohm or 4-20 ma. On off and digital outputs shall be through isolation relays.
The process variable shall be continuously displayed by a 1/32nd din Digital Indicator mounted on the panel.
Two communications ports shall be available if required as RS-232 or RS-485 with the capability of remote initiation by a building management system. The controller shall also have the optional capability of sequencing pumps, positioning combustion make-air louvers, outside air temperature reset, firing rate indication, assured low fire shut down and warm up and night set back/weekend skip. For full modulating control, separate modulating M/A stations shall be available.
