Parts
The following parts are required:
1. Weigh-Tronix IMP-24, Model 2600 printer.
2. 2.25" wide desk top calculator paper.
3. 25 ft. Twisted Pair Shielded Cable (minimum 3 con-
ductor), #18 AWG Stranded, 300V min. insulation.
4. (1 ea.) 25-pin Cannon connector and shell. Connec-
tor: Cannon P/N DB-25P or equivalent. Shell: Can-
non P/N DB-C2-J9.
Assembly and Wiring
All components should be assembled and wired as fol-
lows in Fig. 19. Strip the outside insulation back sev-
eral inches and individual wires about 3/8" to connect
the cable at the Micro Logic Board. Connect the shield
of the cable as shown on the Micro Logic Board. Do
not connect at the printer end of the cable.
Printer Configuration
2 Switches on the printer must be properly configured.
Remove the paper roll to access these switches. Place
the switches in the following position:
SW. 1 OFF
SW. 2 ON
Obtaining a Printout
A printout of current operating data may be obtained
by pressing the OPER DATA key. A snapshot will be
taken by the micro of current operating conditions.
These conditions will be stored in memory until they
can be transmitted to the printer and printed. A sample
printout is shown in Fig. 18 on page 59.

A printout of the fault shutdown history may be ob-
tained by pressing the HISTORY key. A printout show-
ing the last 3 faults with all system conditions at the
time of the fault will be transmitted. A sample printout
is shown on page 58.
An automatic printout will be sent to the printer when-
ever the chiller shuts down on a fault, regardless of
whether the fault causes a system or the entire chiller
to lockout or whether restart is permitted. This is the
same printout that is obtained when the OPER DATA
Key is pressed; however, it will be a snapshot of sys-
tem operating conditions at the instant fault occurred.
Additionally, the Status indication that is noted in the
printout will note the specific fault that occurred.
Using Other Printers
Control codes vary from printer to printer. This will
result in unusual formatting of printed data from many
printers. In addition, "handshaking" lines and "hand-
shaking" sequence will differ between printers. This
makes the equipment susceptible to operation problems
or miswiring which may cause damage to the printer
or the Microprocessor Board. YORK assumes no
responsibility for assistance or damage in the use of
non-specified printers.
Warranty
YORK assumes no warranty responsibility in the use
of the printer. This includes damages to the printer and
the Microprocessor Boards or chiller operation prob-
lems which may result.
