IEC Control Panel with Programmable Logic
Control
This control panel contains a safety disconnect switch,
blower motor control, pulse control functions, and a
Magnehelic gauge. The Programmable Logic Control,
PLC, provides features such as sequential start-up,
staggered aftershift cleaning, and troubleshooting
capabilities.
Blower Control Functions
1. This control panel includes magnetic starters with a
low-voltage control circuit.
2. The blower motor ON/OFF buttons are located on the
control panel cover. A red blower motor RUNNING
light is also provided.
3. Sequential start-up is provided for all DWS 4- and
DWS 6- 2, 3, and 4 modules. This allows a delay
between starting each blower motor and reduces
undesirable overload current at start-up.
4. The control panel has troubleshooting capabilities. If
a blower motor shuts down due to a failure, such as
an overload, the panel will flash the red RUNNING
light quickly. The two amber lights, CLEANING and
AFTERSHIFT CLEANING, will also flash indicating
which circuit tripped the alarm. For example: The
overload on motor protector #3 is tripped. The red
RUNNING light will flash quickly and the two amber
lights, CLEANING and AFTERSHIFT CLEANING,
will flash three times, then pause and repeat. This
indicates that motor protector #3 has been tripped.
The lights will continue to flash until the alarm is
serviced.
5. Thermal overload relays and circuit breakers are
provided for the motor circuit and fuses for the low
voltage circuit. Standard voltages available are
208/230/460/575/60 Hz/3 phase.
