Local Printer Option - York YCRS Series Installation, Operation And Maintenance Manual

5.8 LOCAL PRINTER OPTION

The Micro Panel is capable of supplying a printout of
chiller conditions or fault shutdown information at any
given time. This allows operator and service personnel
to obtain data and system status with the touch of the
keypad. In addition to manual print selection, the mi-
cro panel will provide an automatic printout whenever
a fault occurs. An explanation of the keypad use to ob-
tain a printout is discussed in the "PRINT" KEY Sec-
tion on Page 52.
YORK recommends the field tested WEIGH-TRONIX
IMP-24, Model 2600 printer. This is a compact low cost
printer that is ideal for service work and data logging.
Paper is in the form of a compact roll and is easily
handled compared to larger printers using wider busi-
ness form style paper. The paper is 2.25" wide desktop
calculator paper that can be easily and inexpensively
purchased at most stationery stores. Shown in Fig. 17
and 18 is the WEIGH-TRONIX printer and a typical
sample printout.
The WEIGH-TRONIX IMP-24 Model 2600 printer can
be purchased for approximately $150.00. Contact

ter cooled with or without options.

out which may not be present on the
