2.7 SHUT-DOWN PROCEDURE

The Quickchiller can be shut-down at the end of

the production day whenever any menu screen

which includes STOP=D is displayed.

Before starting unit shut-down, make certain all

product has been removed from the unit. Press

"D" on the keyboard to begin shut-down.

The unit will display a Stop Prompt screen as a

safeguard against accidental shut-down.

Press "C" on the keyboard to continue shut-

down. The Main Menu Screen will appear in

the display.

MAIN MENU SCREEN

The Quickchiller will be ready for start-up as

required and will be fully operational after

allowing 40 minutes to pre-chill before resuming

operations with product.

For prolonged periods of shut-down, thoroughly

clean and sanitize the interior and exterior of the

unit with a mild detergent diluted in warm

water. Maintain the Quickchiller circuit breaker

and branch circuit breaker (Main Panel) in their

ON positions to preserve control data memory. If

power is terminated for more than fourteen (14)

days, and control data memory is lost, refer to

Control Set-Up and Operation, Section 2.0.

2.8 HARDWARE NOTES

NOTE: Refer to Operation and Procedure Guide, Section 9.0.

SERIAL PRINTER:

The printer MUST have an internal buffer of at least 1K

bytes. Since the printer must be able to maintain the same

pace as the control, and there is no printer handshaking,

printers with smaller buffers simply cannot keep up. The

printer must also conform to RS-232 standards and must be

able to print using only the TX and GND lines (i.e., without

hardware handshaking or software handshaking

(XON/XOFF). Nearly all serial printers can print without

handshaking. The printer should be connected to the

control with a NULL serial cable.

RECOMMENDED:

Star Micronics PN# DP-8340 FM

Alto-Shaam Serial Printer & Cable Package PN#14218

PARALLEL PRINTER:

Any EPSON, IBM PRO-PRINTER or compatible is acceptable.

The internal buffer should be at least 1K byte. Most of the

newer printers have at least this amount or more. A standard

printer cable is required. It is not necessary to use a printer

with 24 pins or special graphic capabilities. Alto-Shaam

Parallel Printer Cable (part number 14709) is recommended to

connect parallel printer to Quickchiller control .

DIP SWITCH:

The dip-switch is located on the CPU board. It is read by the

software each time the main menu is entered. Changing the

settings while at the main menu will not effect a change until

the main menu is exited and reentered.

When taking advantage of the special feature program options,

we strongly recommend

individuals with an electronics

background to properly locate

and change dip-switch position.

Refer to Operation and Procedure

Guide, Section 8.1.
