ER SERIES FRYER SERVICE MANUAL SUPPLEMENT - GENERAL GENERAL INTRODUCTION Description Model Designations This Service Manual Supplement covers specific service information only related to the Vulcan Kleenscreen filter models listed on the front cover. The fryer battery utilizes many of the same controls and components as the Vulcan ERD series (solid state control) and ERC series (computer control) fryers. Kleenscreen fryer batteries are available in a minimum of two and a maximum of six fryer sections.
PAGE 4
ER SERIES FRYER SERVICE MANUAL SUPPLEMENT - GENERAL Kleenscreen Filtering System The new "Kleenscreen" filtering system has been integrated into the ER Series fryer battery. The filter is housed in a pull-out drawer assembly at the base of the fryer. The filtering components in the drawer include a stainless steel filter tank, crumb-catch basket and fine mesh screen. With the filter drawer closed, a self-seating return oil line provides the path to return the filtered oil to the fry tank.
PAGE 5
ER SERIES FRYER SERVICE MANUAL SUPPLEMENT - GENERAL SPECIFICATIONS Electrical Separate electrical connections are required for each section of the battery. • 208VAC, 240VAC or 480VAC (3 phase, 60HZ) to power the heating elements. • On 208VAC and 240VAC models, step down transformer(s) provide power for the fryer controls, basket lift(s) if installed, and Kleenscreen filtering controls. • On 480VAC models, a 120VAC connection is required for each fryer section.

ER SERIES FRYER SERVICE MANUAL SUPPLEMENT- SERVICE PROCEDURES AND ADJUSTMENTS SERVICE PROCEDURES AND ADJUSTMENTS COMPUTER CONTROL BOARD DIAGNOSTICS The computer control is used on other equipment and is capable of displaying many different prompts. Therefore, some prompts not applicable may display when a problem occurs in the wiring harness. Since the computer is looking for either 24 VAC or 24 VAC ground on particular pins, an open connection can cause a nonapplicable prompt to appear.
PAGE 9
ER SERIES FRYER SERVICE MANUAL SUPPLEMENT - ELECTRICAL OPERATION Power up Diagnostics On power up, the control will execute a self check. The failure of any of these tests will result in the message “CALL SERVICE” or “MICRO FAIL” being displayed. This prompt will flash at approximately a 1 hertz rate. While the prompt is displayed, the computer will not function. If the failure is in the computer, the fryer will operate in backup mode.

B. 5. 1) Power to pins 3, 4, 5, 6, 11, and 17 (control system main input) on computer main harness.
PAGE 12
ER SERIES FRYER SERVICE MANUAL SUPPLEMENT - ELECTRICAL OPERATION 2) NOTE: Pins 1 and 2 on the main harness are used to monitor the power switch "status" of the vat(s). Pin 1 is the power status input on a full vat or right side split vat and pin 2 is the input for the left side split vat only. These inputs tell the computer which vat(s) are turned ON or OFF. 3. A. Computer control evaluates the input from thermistor then activates the 24VAC output from pin 15 and power is applied to R2 control relay.
