X13 ECM Constant Torque Motors
The X13 is a ‘Constant Torque’ ECM motor and delivers air flow
similar to a PSC but operates as efficiently as an ECM Variable
Speed Motor. Because it’s an ECM Motor, the X13 can ramp
slowly up or down like the ECM Variable Speed Motor. There are
5 possible speed taps available on the X13 motor with #1 being
the lowest airflow and #5 being the highest airflow. These speed
selections are preset at the time of manufacture and are easily
changed in the field if necessary. The G, Y1 and W signals are
wired to the motor at the factory. A gray wire is tied to the motor
wire bundle for the Y2 signal and can be field connected to the
motor if desired.
X13 Benefits:
- High efficiency
- Soft start
- 5 speeds with up to 4 speeds on-line
- Built in logic allows air flow to change with G, Y1, Y2
and W signals
- Super efficient low airflow continuous blower
setting (G)
If more than one tap are energized at the same time, built in logic
gives precedence to the highest tap number and allows air flow
to change with G, Y1, Y2 and W signals. Each of those 5 speeds
has a specific ‘Torque’ value programmed into the motor for each
speed selection. As static pressure increases, airflow decreases
resulting in less torque on the rotor. The motor responds only to
changes in torque and adjusts its speed accordingly.
The X13 motor is powered by 208-230VAC but the motor speed is
energized by 24VAC.
Power Connection - 3/16 in. quick connects - Line 1 (orange wire)
to L, Ground (green wire) to G, Line 2 (for 208V-230V units) to N
(brown wire).
Signal Connection - 1/4 in. quick connects - Common to C, 24VAC
to Taps #1-5.
Applying 24VAC power between any of the motor taps 1-5 (1/4
in. quick connects) and common will signal the motor to run and
regulate torque at the programmed level. The tap input voltage
must be in the range 12-33VAC. The X13 will have less variation
over the operating static pressure range versus a PSC motor
as well as a significant watts reduction due to the high motor
efficiency.
Thermal protection - Motor is electronically protected.
Locked Rotor Amps - If motor speed decreases below a
programmed stall speed, the motor will shut down and after a
delay period, the control will attempt to restart the motor.
The X13 speed tap selections are as follows:
The blue wire should be placed on the speed tap desired for the
(G) continuous blower setting – factory wired to Tap 1.
The red wire should be placed on the speed tap desired during
compressor operation (Y1 signal) – factory wired to Tap 3 or 4.
The gray wire is not factory wired to the motor and is tied to the
wire harness. It is field connected and can be used with 3ht/2cl
thermostats or IntelliZone to deliver the required air flow for the Y2
signal.
The tan wire should be placed on the speed tap desired for
auxiliary heat (W signal) – factory wired to Tap 5.
