Electrical Connections
Components require 12V or 24V DC (nominal), depending on the model. The ignition enable is a switched power
source which is sent from the vehicle or system to initiate operation of the component. This can be wired directly
to a vehicle ignition, to a PLC output, through a manual switch or through a thermal switch. This line will draw
less than 10 mA of current. All switches on this line can be sized based on this amperage requirement. This input
should be fused close to the source to protect the vehicle or system wiring.
The following sections provide information about how to implement supported control strategies. PWM,
TACH_OUT and EMP-Link require additional pin connections.
On/Off Single Speed Control
NOTE:
All cavities in the mating connector(s) must either be
terminated or plugged to prevent moisture from entering the
component.
NOTE:
10 AWG wire can be used for power and ground. Use
Delphi 480 cable seal #15324990.
Example On/Off Application Schematic
Operation
NOTE:
Holding pin
B
low will cause the component to produce the TACH_OUT diagnostic output. See
for a description of the TACH_OUT.
When power is on and ignition enable is on, the component will run in an on/off, single speed manner. The speed
at which the component will run will be the pre-configured default speed.
NOTE:
For assistance with component calibrations and settings, please contact EMP Technical Service at
and provide a serial number for the part in question.
