Do not run the evaporator fan motor be-
low 30Hz, as coil freeze-up and nuisance
lockouts may occur. The unit is factory set
to minimum 30 Hz output with the excep-
tion of the Low Ambient Condenser VFD,
which is set to 15 Hz.
The unit does not carry a failsafe circuit
to bypass the VFD and run the evaporator
fan in the event of a VFD malfunction.
The unit does not carry a failsafe circuit bypass for the
evaporator fan in the event of a VFD malfunction. Dur-
ing a VFD failure, the evaporator fan becomes non-
operational. If there is a demand for cooling, the unit
compressors continue to run until the low pressure
safety switch trips.
FACTORY SHIPPED
Units that are 8 tons or larger ship with a VFD control-
ler factory installed and wired in the evaporator (air
handler) corner post. See the dimensional drawings in
the IOM for the location.
DSV MODELS
The DSV units ship factory split (condenser and evap-
orator) and require assembly in the field. The motor is
pre-wired to the VFD in the factory.
To assemble the DSV model in the field:
1. Plug the low voltage wiring, shipped wired to the
VFD, to the SE Controller.
2. Connect the low voltage wires from VFD unit
(24VDC) to the evaporator fan VFD relay (EVF-
DR). The EVFDR relay acts as a switch to turn on
the VFD.
3. Connect two 1/4 inch Q.C. to common and nor-
mally open positions (red wire to “C,” orange
wire to “NO”).
The VFD switch runs on 24VDC.
Do not cross 24VAC and 24VDC wiring
on EVFDR relay.
SECTION 1 - INSTALLATION
Do not enter Setup mode when powering
on the VFD.
Do not change parameters 4009 and 4011
for the VAV option on DSH/DSV C-gen
units.
For these units, use the Smart Equipment
(SE) controller to set the VAV setpoint.
Prior to installing or servicing the unit,
ensure proper lockout/tagout (LOTO)
procedures are followed per OSHA
safety regulations (29 CFR 1910.147 and
29 CFR 1910.333). Failure to disconnect
power supply may result in electrical
shock or even death.
Always wait for at least 5 minutes after
disconnecting the power before servicing
the unit.
BACKGROUND
All D-Series and C-Series units that are 8 tons or larg-
er have a Variable Frequency Drive (VFD) installed.
There are 2 Controlled Fan Method VFD options: VAV
differential pressure transducer and discrete speed (3 or
4 speed) fan control.
Refer to the nomenclature breakdown in
the appropriate DSV/DSH Installation,
Operation, and Maintenance (IOM)
manual and also the nameplate of the unit
to determine the Controlled Fan Method.
The tenth digit of the nomenclature (ID
Motor) identies which method the unit
has.
Use the nomenclature to select the low
ambient condenser option.
For units with the VAV option, the supplied VFD al-
lows the operator to set the external static (0.0–2.5
"WC), as measured from a supply duct location deter-
mined by field installer and/or as per field specifica-
tions. The VFD controls the frequency (speed) of the
evaporator fan motor in order to meet the desired exter-
nal static (ESP) setpoint. The VFD controls amps draw
of the motor and does not allow the motor draw more
than nominal amps.

SECTION 1 - INSTALLATION
DSH MODELS
The VFD controller on DSH units is factory wired. The
evaporator fan power conductors are factory wired to
the distribution block. The control wiring for field split
applications needs to be field provided and routed from
condenser to evaporator.

FIGURE 1 - LABEL ON UNIT/VFD FOR VAV WITH
PRESSURE TRANSDUCER
For VAV option units, the differential pressure trans-
ducer is factory wired and mounted inside the VFD
control box. The transducer senses gage pressure (stat-
ic) and converts this pressure difference to an analog
signal. The unit is wired for 0–5VDC output for DSV/
DSH C-gen units.
The transducer is supplied with two 1/4-inch OD pres-
sure fittings and accepts field provided 1/4-inch push-
on tubing for lengths of up to 300 feet. The positive
(HIGH) and negative (LOW) pressure ports are indi-
cated on the transducer. Connect unit RETURN AIR
tubing to negative (LOW) fitting and SUPPLY AIR
tubing to positive (HIGH) fitting.
• Only on 208/230-460 VAC units; not on 575 VAC
• 4009 and 4011 are parameters within the
ABB VFD drive and are factory set at
0.5 ”WC. These eld adjusted points are adjusted
at start-up. These setpoints are based on system
requirements.
Example: If the Supply Duct Static Pressure is
designed for 1.0 "WC, set both Parameters 4009
and 4011 to 1. Adjust Parameters 4009 and 4011
up or down accordingly until the required setpoint
is achieved. Once the setpoint is adjusted, docu-
ment Parameters 4009 and 4011 for future refer-
ence.
Do not adjust the VFD setpoint to greater
than the maximum design pressures of the
duct system or the unit.
• Only use 24VAC from SE controller to the differ-
ential pressure transducer (Term. Exc.)
• Set S1 jumper on VFD, AI1, to Volts
• The VFD is enabled by the Evaporator Fan VFD
Relay (RVFD)

FIGURE 2 - LABEL ON UNIT/VFD FOR MULTI-
SPEED FAN CONTROL
Figure 2 is an example of a label.
C-gen units are 3 or 4 speed depending
on staging.
The multi-speed Fan Control is available on all 8 ton
DSH and DSV units.
For the 15–25 ton DSV units and 10 ton DSH with four
refrigeration stages, the evaporator fan runs at 50%,
60%, 75%, and 100% speed.
For 8–12 ton DSV units and the 8 ton DSH unit with 3
refrigeration stages, the evaporator fan is set to run at
50%, 60%, and 100% speed.
The 2–5 ton DSH units and 5 ton DSV unit do not have
a VFD as a standard and operate at single fixed speed
(100%).
VFD KEYPAD
The VFD requires a keypad to program the VFD. The
keypad is not required to operate the unit when the
VFD is programmed. The keyboard is required dur-
ing initial startup of the unit. Each unit comes with a
factory installed and programmed remote keypad and
short Ethernet clip on connector. An Ethernet commu-
nication cable is supplied by the factory. You can use a
single keypad to program multiple units. Consult with
your sales office to order additional keypads. A copy
of the factory default settings is saved to the keypad
memory available for restore if needed.

INSTALLATION
For units utilizing the VAV option, install a field sup-
plied 1/4-inch push-on tube to the return air side of the
unit. Pass the tube through the opening on the side of
the corner post adjacent to the VFD controls, and con-
nect to the negative (LOW) side fitting.
Install a field supplied Pitot tube in the supply duct as
required, run 1/4-inch push-on tube to the corner post
opening, and connect to the positive (HIGH) side fit-
ting.
LD20863
FIGURE 5 - CONNECTING NEGATIVE AND
POSITIVE SIDE FITTINGS
Check that the tubes are secure inside the duct and
firmly connected to transducer fitting. If they are not,
the unit will not operate as intended.
INSTALL GRILLE COVER
When the unit is wired and the push-on tubing is con-
nected to the transducer, attach the grille cover using
the screws provided, with angled blades point upward
at the top.
