LEAD/LAG CONTROLLERS MODEL PSP & BSP

GENERAL DESCRIPTION:

Toxalert has two basic lead/lag controller types. One designed for dual circulating pumps and the

other to automatically sequence boilers when they are to be controlled in a lead/standby sequence.

ON-OFF AUTO:

Both controller types feature an internal ON-OFF-AUTO switch mounted on the printed circuit board

that operates the controlled equipment. In the “AUTO” position the controller automatically operates

the controlled equipment via a SPST outdoor air thermostat. In the “ON” position the equipment is

positively turned ON, and positively turned off in the “OFF” position. The ON-OFF-AUTO switch

function can be remotely controlled by installing a three position switch remote from the Lead/Lag

controller (See technical description).

LEAD/LAG:

The LEAD/LAG switch is also mounted on the printed circuit board and is designed to choose the lead

equipment. With the switch in the R-1 (relay #1) position, pump #1 or boiler #1 is in the LEAD

position and equipment operated by relay 2 is automatically in the lag or standby position. With the

switch in the R-2 position the equipment (pump or boiler) operated by relay #2 is in the lead position,

and equipment connected to R-1 automatically becomes the lag or standby equipment. The

LEAD/LAG switch function may also be controlled remotely by simply installing a remote SPST

switch. (See technical description.)
