Electrical Data
External Demand Limit Setpoint
(EDLS) Option
Unit auxiliary controller (1A4) provides a means to
limit the capacity of the chiller by limiting the number
of compressors or stages than are allowed to run. The
maximum number of compressors allowed to run can
vary from one to the number of stages on the unit. The
staging algorithm is free to decide which compressor or
stage shall be turned off of prevented from running to
meet the requirement.
Unit auxiliary controller (1A4) shall accept either 0-20mA
or 4-20mA signals. Each signal corresponds to an EDLS
range with a minimum of 1 compressor and a maximum
of all compressors. The following tables exist:
ECWS and EDLS Analog Input Signal
Wiring Details
Both the ECWS and EDLS can be connected and set up as
either a 2-10 Vdc (factory default) , 4-20 mA, or resistance
input (also a form of 4-20 mA) as indicated below. (Need
to indicate here how to switch from Vdc to mA on PC05)
