STT 800 6. Functional description This functional description is intended for all operating personnel of the equipment. Prerequisite for this functional description is general knowledge of dryers and SPS (PLC) systems. SM2-625 Ensure in each case that the operating personnel are sufficiently informed.
STT 800 6.1. Dryer The dryer operates with dehumidified air, i.e. the air is not only heated but also dehumidified before flowing into the drying hopper. This principle allows plastic granules to be dried to a residual moisture content as low as 0.002 % (PET granulate). The dryer operates continuously, i.e. dehumidified and, if necessary, heated air is produced continuously. F The dryer is designed for continuous operation.
STT 800 6.2. Drying hopper (optional) The material is dried in the drying hopper. The dehumidified air is forced through the material in the hopper, collecting moisture in the process. The drying hopper must be dimensioned according to its intended use to ensure that the final moisture content is attained. When the hopper is filled for the first time or at the start of a drying procedure, the material in the hopper must be dried completely before material can be removed from the hopper for the first time.
STT 800 6.3. Return air cooler (optional) F A return air cooler is generally required in cases in which the return air temperature is over 65 °C (149°F). A return air cooler improves the efficiency of the drying cells. The return air cooler reduces the return air temperature to a defined value. The return air temperature is set at the operation panel. & The lower the value chosen for the return air temperature, the better the efficiency of the drying cells.
STT 800 6.5. Hopper heaters (optional) If differing drying temperatures are required in the different drying hoppers, hopper heaters must be installed on the drying hoppers. The drying temperature of each drying hopper can be set centrally at the dryer. 6.6. Automatic motor flaps (optional) Automatic motor flaps cut off the drying hopper from the drying circuit as soon as the material is completely dried. The supplementary heating system is also switched off.
Dehumidified Air Dryer 7. Transport, Assembly and Storage » This chapter is intended for all operating personnel of the equipment. Personnel using these instructions must be instructed in the regulations for the prevention of accidents, the operating conditions and safety regulations and their implementation. Ensure in each case that the operating personnel are sufficiently informed.
Dehumidified Air Dryer 7.1. Transport and Packing » Please ensure adequate carrying capacity of the lifting equipment. Note that the dryer system is top-heavy. Risc of toppling! The equipment pass a rigorous operating test in the factory and are packed carefully to avoid transport damage. Please check packing on delivery for transport damage. The inlet and discharge flanges are sealed with plugs, so that no dirt can enter during transport. Plugs must be removed before assembly.
Dehumidified Air Dryer with a workshop crane Check if the eyelets are installed on the dryer housing. If this condition is met, fasten the transport cables to the eyelets. If this condition is not met, mount the eyelets and then fasten the transport cables to the eyelets. Disassemble the eyelets after set-up.
Dehumidified Air Dryer 7.2. Assembly » Please ensure adequate carrying capacity of the lifting equipment. Check the carrying capacity of the point of installation, particularly if installed on a platform. The place selected for installation should be as free of vibrations as possible. The main switch must be freely accessible. Ground the equipment against electrostatic charging. A special foundation is not required for installation.
Dehumidified Air Dryer 8. Assembly instructions » These installation instructions are intended for persons with skills in electrical and mechanical areas due to their training, experience and received instructions. Personnel using these installation instructions must be instructed in the regulations for the prevention of accidents, the operating conditions and safety regulations and their implementation. Ensure in each case that the personnel are informed.
Dehumidified Air Dryer 8.1. Mounting of the suction device for regeneration exhaust air When plastics are dried which produce hazardous gases, environmentally sound disposal of the regeneration exhaust air must be provided. The throughput of the regeneration blower may not be changed. It must be taken into consideration when installing a disposal system (e.g. exhaust system) that regeneration exhaust air is extremely humid.
Dehumidified Air Dryer 8.3. Electrical connection » Observe the rules of the local electricity board. Check that the supply voltage and the power frequency are in accordance with the data on the name plate of the device. The electrical connection may only be carried through or assigned by Sterling service staff or by qualified staff authorized by Sterling. Other persons are not permitted to carry through the electrical connection. The main switch must be freely accessible.

Accessories 02/01GB Entering values on the OP 7 / 17 Sterling Material Processing
General Operation 3.3 Entering Values General procedure In input fields, values can be entered on the OP and transferred to the PLC. To do this, proceed as follows: Step Procedure 1 Branch initially to the screen you require and then to the corresponding screen entry. 2 Using the arrow keys, select the input field you require within the screen entry. 3 Then enter your value. Depending on how the field has been configured, values may be input as inputs of numerical values (refer to section 3.3.
General Operation 3.3.1 Entering Numerical Values Input using numerical keypad In fields that allow the operator to enter a numerical value, you enter the numerical value character by character using the keypad on the system keyboard. Changing the value If there is a value in the field already, it is cleared completely from the field when the first character is entered. Once input has been started, you cannot exit from the field until the input has been entered or canceled.
General Operation 3.3.2 Entering Alphanumeric Values Mixed input of digits and letters With the input of alphanumeric values, digits and letters are mixed. Entering A to F characters A to F characters can be entered directly with activated Shift Lock mode using numeric keys 1 to 6. If you want to enter digits again after the letters, Shift Lock mode must be de-activated.
General Operation Extended character set If the characters available on the keypad are not sufficient for the alphanumeric input, you can select additional letters and special characters from the extended character set. The extended character set is available for all KC type fields. To enter the string 18OKT61, for example, proceed as follows: Step Procedure 1 Press in succession 2 Press Shift-LED is on. 1 A 8 \ The extended character set is available.
General Operation 3.3.3 Entering Symbolic Values Text instead of a value When you enter a symbolic value, text is displayed instead of the value. If a field has to be filled by entering symbolic values, take the value from a list of options. To do so, proceed as follows: Step 1 Procedure In the input field press Shift LED is on. \ The list of options with its configured symbolic inputs is activated. 2 Select the value you require using the arrow keys.
