Chromalox C4 Quick Start Manual

C4 4-Channel SCR Power Controller with
Independent PID Control Quick Start
Manual 0037-75569 (PK541)
This manual is intended to be a quick reference guide for basic installation require-
ments and an overview of the connections, wiring considerations, and general spec-
ifications for the C4 4-Channel SCR Power Controller with Independent PID control.
For complete installation and operation, refer to the PK544 C4 Hardware Instruction
Manual. For complete configuration and programming refer to the PK548 C4 Con-
figuration and Programming Manual. The most current revisions may be found on

1. IMPORTANT SAFEGUARDS
ELECTRIC SHOCK HAZARD: Read and understand all instructions before
installing, servicing or operating this controller. Failure to do so could
result in equipment or property damage as well as personal injury and
even death.
HIGH VOLTAGE is used in the operation of this equipment. DEATH ON
CONTACT may result if personnel fail to observe safety precautions.
Learn the areas containing high-voltage connections when installing or
operating this equipment.
Be careful not to contact high-voltage connections when installing or
operating this equipment. Before working inside the equipment, turn
power off and ground all points of high voltage potential before touch-
ing.
ELECTRIC SHOCK HAZARD. Any installation involving control equip-
ment must be performed by a qualified person and must be effectively
grounded in accordance with the National Electrical Code to eliminate
shock hazard.
The Owner/Installer must provide all necessary safety and protection
devices and follow all current electrical wiring standards and regula-
tions. Failure to do so may compromise the integrity of the controller
and/or cause product failure resulting in a safety risk to operational
service and personnel.
This controller utilizes a heat sink which is designed to cool the unit
during operation. Under no circumstance should air flow around the
controller be compromised in any way. Failure to do so may result in the
overheating of the controller, product failure, product temperatures and
even fire.
During continuous operation, the heat sink can reach a very high
temperatures, and keeps a high temperature even after the unit is
turned off due to its high thermal inertia.

Installation Wiring Note:
Use the extra rapid fuses as indicated in the C4 Hardware Instruction Manual PKXXX,
according to the wiring schematic examples and controller rating. Additionally, the
applications with solid state units require safety automatic switch to disengage the
load power line during certain alarm events.
Before and during the inspection/ maintenance cut power to the fan
controller and verify that the system is isolated for operator safety.

must be accessed. Follow these steps:
1. Remove the Fieldbus compartment cover screw 16
2. With a flat screwdriver, gently apply pressure at 18
3. Remove compartment cover 17
4. Insert Fieldbus card 19 into the proper connector 21
5. Remove applicable communication port tab 20 on cover 17
6. Carefully replace compartment cover 17

COOLING FAN CARE
Periodic Cleaning
Every 6-12 months (depending on the
dust level of the installation) blow a com-
pressed air jet downward through the up-
per rectangular cooling grilles (on the side
opposite the fan). This will clean the inter-
nal heat dissipater and the cooling fan.
In Case of Overheat Alarm
If periodic cleaning does not eliminate the
problem, do as follows:
a. Remove the fan support grille by
detaching the two support tabs
b. Disconnect fan connector from board
c. Check the condition of the fan
d. Clean or replace the fan (*)
e. Insert the connector into the board
f. Insert fan support grille until it attaches
g. Power up the device and check fan
rotation when at least one load is on
