provides an inexperienced technician (training is required for all who work on the foam systems)
very detailed steps to perform the task.
ALWAYS DISCONNECT THE POWER CABLE, GROUND STRAPS, ELECTRICAL WIRES AND
CABLES FROM THE CONTROL UNIT OR OTHER HALE SAM EQUIPMENT BEFORE ELEC-
TRIC ARC WELDING AT ANY POINT ON THE APPARATUS.
4.3.1
Tag And Disconnect Electrical Connections
ALL ELECTRICAL SYSTEMS HAVE THE POTENTIAL TO CAUSE SPARKS DURING SERVICE.
TAKE CARE TO ELIMINATE EXPLOSIVE OR HAZARDOUS ENVIRONMENTS DURING SER-
VICE AND/OR REPAIR.
KEEP ALL I/O PORT COVERS IN PLACE DURING USE TO PREVENT WATER DAMAGE.
OTHER ELECTRICAL COMPONENTS MUST NOT BE SUPPLIED FROM THE SAM SYSTEM
SUPPLY. DO NOT CONNECT THE PRIMER AND HALE SAM TO THE SAME POWER WIRE.
THE CONTROLLER UNIT DEUTSCH CONNECTORS ARE KEYED TO PREVENT INTER-
CHANGE OR REVERSE DIRECTION INSERTION. DO NOT FORCE A CONNECTOR WITH-
OUT FIRST VERIFYING THE CONNECTORS ORIENTATION AND PLACEMENT.
THE MODULE DEUTSCH CONNECTORS ARE KEYED; HOWEVER, ALL MODULES UTILIZE
THE SAME TWO KEYS. VERIFY THE HARNESS LABEL AND THE MODULE PART NUMBER
TO ENSURE THE CORRECT MODULE AND HARNESS CONNECTOR ARE BEING CON-
NECTED.
Never attempt to tag, disconnect, or connect an energized circuit.
As a general maintenance practice, tag (document/photograph/record) the connector orientation
and location (including the mating connector) for each component before disconnecting or re-
moving it.
From/To wire listings (pinout) listings are provided for modules, sensors, solenoids, etc., when a
listing is not present herein, refer to the plate drawings located in the SAM PM (FSG-MNL-00212)
for the devices signal listing and harness information. The SAM PM can be found on the Hale
website (www.haleproducts.com) or on the flash drive provided with the system.
4.3.2
Tag And Disconnect Pneumatic (Air) Connections
SAM utilizes apparatus compressed air. As a general maintenance practice, tag (document/pho-
tograph/record) the connector orientation and location (including the mating connector) for each
component that utilizes air pressure before disconnecting or removing it.
4.3.3
Tag And Disconnect Drain Connections
THE SAM DRAIN VALVE BLOCK IS CONNECTED TO THE APPARATUS COMPRESSED AIR
SUPPLY VIA A 4-WAY AIR VALVE. DO NOT REMOVE A 4-WAY AIR VALVE, PF VALVE AIR
CYLINDER, FITTINGS, OR AIR TUBES WHEN THE SYSTEM IS PRESSURIZED.
