STS-200 Steamer/Scale Maintenance Precaution: During these checks, hot surfaces will be exposed. Hazard Communication Standard (HCS) – The procedures on this card include the use of chemical products. These chemical products will be highlighted with bold face letters followed by the abbreviation (HCS) in the tools portion of the procedure. See the Hazard Communication Standard (HCS) Manual for the appropriate Material Safety Data Sheet(s) (MSDS).
STS-200 Steamer/Scale Maintenance (continued) Daily Maintenance IMPORTANT Turn off the power, unplug the power cord, and allow the unit to cool down before proceeding. Cleaning the Steamer Scale 1. Check the Water Quick Disconnect Fitting and all hose clamp connections for leakage. If leakage is apparent, tighten all clamps or replace part if required. Figure 4. Dirty Steam Generator 2. Remove the Top Cover and Diffuser and wash in a solution of Steam Generator Cleaner (HCS). 3.
STS-200 Steamer/Scale Maintenance (continued) 5. Use a stainless steel wire brush to loosen and remove excessive deposits from the Steam Generator surface. Then, reinstall the Diffuser. Cleaning the Water Inlet Tube Sometimes when cleaning the Steam Generator, small particles may be pushed into the Water Inlet Tube, causing it to become clogged. 6. Pour Delimer/Scale Remover (HCS) so that it just covers the top of the Diffuser.
STS-200 Steamer/Scale Maintenance (continued) Monthly Maintenance Checking/cleaning the water strainer The Water Strainer protects the unit from any foreign debris in the water line that could get into the food, damage the unit’s solenoid (causing the unit to leak or flood), or interfere with the equipment’s proper and consistent operation. To ensure proper and consistent steaming results, check the Water Pressure Regulator and Strainer Cup regularly.
STS-200 Steamer/Scale Troubleshooting Message Codes The table below lists the possible message codes displayed by the unit during operation. Contact the factory if you have any questions about these message codes. Message Code Description 888 Display test, all digits on. 93 Software part number, DSW0093. r0.3 Software revision. Ld0 Loading zero, shown on start up. don Indicates that calibration is complete. SAv Indicates that the current values are saved into memory.
STS-200 Steamer/Scale Troubleshooting (continued) Problem The unit heats up and steams but the front display is blank. Possible Cause(s) Faulty scale Control Board. Faulty temperature Control Board. Disconnected/Loose wiring harness. Unit operates, but the front display intermittently goes blank then comes back on after several minutes. Corrective Action Contact your maintenance person or an Authorized Service Agency for service.
STS-200 Steamer/Scale Troubleshooting (continued) Problem Scale is not weighing properly and/or behaves erratically. Unit heats, does not steam, but the Green LED at the rear of the unit DOES turn on for a split second as the air bulb is pressed. Possible Cause(s) Corrective Action Scale requires calibration. Calibrate scale according section titled “Calibrating the Steamer Scale” in the Operation section of this manual.
STS-200 Steamer/Scale Troubleshooting (continued) Problem Possible Cause(s) Corrective Action The unit is not steaming the product properly and/or the product requires re-steaming. The Water Pressure Regulator is improperly set. Adjust regulator to 7-9 PSI. Refer to the section titled “Adjusting the Water Pressure Regulator” in this manual. The water regulator strainer screen is clogged. Clean the strainer according to the Maintenance section of this manual. Rotary switches are not correctly set.
STS-200 Steamer/Scale Technical Theory of Operation Technical Theory of Operation The multifunctional Control Board incorporates two status LEDs detailed below. If the heating circuit continues to call for heat and the Generator overheats, an automatic resetting Hi-Limit Thermostat will trip and open the generator circuit and transformer circuit at approximately 450-470º F (232-243ºC).
STS-200 Steamer/Scale TEchnical Theory of Operation (continued) Blue light blinking codes (Refer also to the Troubleshooting Section) Led Function (The following LEDs are viewed from the rear of the unit) Rapid Flashing: Under this condition, the generator may, or may not get hot. The solenoid valve circuit is disabled until the cause is corrected. Yellow (Heat): When lit, it indicates that the unit is in heat mode. During this time, line voltage is being supplied to the generator.
