It is recommended you program this fan with
a higher Cut In setpoint than condenser fan #1,
so that this fan will come on as a second stage.
Fan 2 Cut Out
Fan 2 Cut Out sets the deactivation setpoint
for condenser fan #2. When the discharge pres-
sure falls below the Cut Out setpoint, the fan will
turn OFF.
Fan 2 Minimum ON Time
The Fan 2 Minimum ON time is the smallest
amount of time condenser fan #2 must remain
ON after being activated.
7.3.3. Screen 3: Inputs
Figure 7-5 - Screen 3: Inputs Screen
The Inputs screen is where special data shar-
ing connections between the CUB and E2 or
Einstein must be set up for motor room control,
outside air temperature sharing with Global
Data, and reading remote inputs from the CUB
board that may be read by other E2 or Einstein
applications.
MOTOR RM TEMP
This input name will have a number after it
from 1-4, which is the same number as the motor
room zone number you programmed for this
CUB in Screen 1. This input reads from the par-
ent E2 or Einstein's Global Data the value of the
motor room temperature, provided there is a
CUB in the zone with a motor room temperature
sensor.
Programming The CUB Using the E2 or Einstein Front Panel
This input is automatically configured, and is
primarily displayed in this screen as a reference.
REMOTE INPUT
The Remote Input is passed to any of the
CUB's outputs that are set up as "Remote" type
outputs. When this input is tied to a digital out-
put from another E2 or Einstein application, it
will cause all "Remote" outputs on the CUB
board to mirror the digital state of the digital out-
put.
Enter the controller, application, and prop-
erty address of the remote input in this field.
PLENUM TEMP
The plenum temperature input provides the
CUB the current value of the ambient tempera-
ture used for TD calculation.
Because plenum temperature will likely be
measured by one temp sensor and will be shared
with multiple CUB-IIs and CUB-TDs, it is rec-
ommended the plenum temperature sensor itself
is physically connected to Global Data's Spare
Analog inputs, and the plenum temperature input
definition be set up to receive its value from
Global Data. Refer to Set Up Motor Room Tem-
perature and Plenum Temperature Inputs on
page 62 for special instructions on setting up
plenum temperature in Global Data.
