Notes
Condenser Fan
(Single-Speed)
N.C. N.C. (up) To ensure condensing during network and power failure,
co
ndenser fans should all be configured normally closed
(N.C.)
Condenser Fan
Relay (V

Speed)
N.C. N.C. (up) The fan should operate at 100% during loss of communi-
cation with E2.
Dampers (Evap.

y)
N.C. N.C. (up) Dampers should be open during communication loss
(N.C.).

N.C. (see note) N.C. (see note) Some condensers have dual pumps that cycle at even
intervals. One pump should be wired N.C. and the other
N.O., so that only one pump runs during communication
loss.

11.3 Standard Circuits
Refrigerated cases that do not use case controllers are
controlled by Standard Circuit applications. In a Standard
Circuit application, the E2 is responsible for all case mon-
itoring and control; it uses the RS485 I/O Network to both
gath
er case temperature inputs and activate or deactivate
the liquid line solenoids, defrost modes, and fans. Also,
circuits that use ESR8s and MultiFlex ESRs are controlled
using Standard Circuits.
NOTE: Do not set up a Standard Circuit appli-
cation for a case that uses a CC-100 or CCB
case controller. These cases must use Case Cir-
cuit Control applications (see Section 11.4, Case Con-
trol Circuits).
