ECM Overview and Setup
DLSC-IOM-13.0
Remote PWM Signal Interface Board Details
Jumpers
M – Enables SET SPEED potentiometer
manual override (bypassed when
automation SIGNAL exceeds 0.2VDC).
S – Enables SET SPEED potentiometer
reversal (used when the set speed
potentiometer is going to be adjusted
from the component side of the board).
P – Enables hysteresis option
With P Jumper: Configures the SIGNAL
input to a 2-10v range; corresponding to
0-100% motor speed request.
Without P Jumper: Configures the
SIGNAL input to a 0-10v range;
corresponding to 0-100% motor speed
request.
Input / Outputs
Input
Power Supply: 18-30 VAC, 60Hz
SIGNAL & COMMON: 0-10VDC = 0-100% PWM request
ECM supplied feedback: 5VDC (motor at rest or not connected)
Output
PWM supplied to ECM: 18VDC (10mA max)
ON/OFF supplied to ECM: 18VDC (10mA max)
RPM & COMMON: 0-10VDC (5mA max) = 0-2000 RPM (10
RPM increments)
DDC Control – Air Balance
If the DDC Controller signal is already installed, air balance can
be achieved using the DDC Controller software tools. Please
notice that a control signal less than 0.2Vdc may put the
interface board into manual override. Avoid setting the DDC
signal to less than 0.2Vdc.
Cycle Power ON/OFF for faster lockout Removal
Manual Air Balance
The interface board can be manually adjusted before the DDC
Controller signal is available. The balancer’s manual adjustment
has authority until automation is connected.
Air Balancer
1. Use adjust to set the air flow. This adjustment will
have authority for at least 15 minutes
2. Read the flashing green light and record the flow index
on the air balance report.
DDC Integrator
1. Set the Signal to 0Vdc to invoke manual override.
2. Record the RPM on the air balance report.
3. Enter the flow index the air balancer entered on the air
balance report.
4. Observe the RPM is at or near the RPM observed in
step 2.
5. Cycle the motor on/off 5 times. This clears the manual
override function unless the “M” jumper is in
place.
Turning Adjust potentiometer locks out the BAS
signal for 15 minutes
