INTRODUCTION AND OPERATION

Part No. 001-2001-200
can be returned to the factory for repair. However, it is
recommended that you contact the Field Service
Department before returning equipment. A service
representative may be able to suggest a solution to the
problem so that return of the equipment would not be
necessary.
Be sure to fill out a Factory Repair Request Form
#271 for each unit to be repaired, whether it is in or
out of warranty. These forms are available free of
charge by calling the repair lab (see Section 1.7) or by
requesting them when you send a unit in for repair.
Clearly describe the difficulty experienced in the
space provided and also note any prior physical dam-
age to the equipment. Then include a form in the ship-
ping container with each unit. Your phone number and
contact name are very important because there are
times when the technicians have specific questions
that need to be answered in order to completely iden-
tify and repair a problem.
When returning equipment for repair, it is also a
good idea to use a PO number or some other reference
number on your paperwork in case you need to call
the repair lab about your unit. These numbers are ref-
erenced on the repair order and it makes it easier and
faster to locate your unit.
Return Authorization (RA) numbers are not nec-
essary unless you have been given one by the Field
Service Department. They require RA numbers for
exchange units or if they want to be aware of a spe-
cific problem. If you have been given an RA number,
reference this number on the Factory Repair Request
Form sent with the unit. The repair lab will then con-
tact the Field Service Department when the unit
arrives.
1.9 REPLACEMENT PARTS
E.F. Johnson replacement parts can be ordered
directly from the Service Parts Department. To order
parts by phone, dial the toll-free number and then
enter "1" as described in Section 1.7. When ordering,
please supply the part number and quantity of each
part ordered. E.F. Johnson dealers also need to give

If there is uncertainty about the part number,
include the designator (C112, for example) and the
model number of the equipment the part is from (refer
to Section 1.4).
You may also send your order by mail or FAX.
The mailing address is as follows and the FAX num-
ber is shown in Section 1.7.

cable to the COM1 or COM2 port.
Reset
S1 provides a manual reset of the Main Processor
Card (MPC). A manual reset causes a complete
power-up restart.

Each combination of DS1 display read-out and
CR4/CR5 indication refers to an active alarm. See
Table 1-2 for alarms and definitions. LED indica-
tions: CR1 is blinking; MPC is operational, CR2 on;
