Scilogex Digital Hotplate-Stirrer SCI550-Pro Display

Note: If both heating and stirring functions have been started at the same time, heating function always has higher priority. If in this case speed is changed via the stirring knob, it displays stirring speed and reverses to temperature in the duration of 5 seconds.

Trial run

• Make sure the required operating voltage and power supply voltage match.
• Ensure the socket must be properly grounded.
• Ensure the power is off.
• Plug in the power cable,ensure the power is on and begin initializing.
• Add the medium into the vessel with a stirring bar.
• Place vessel on the work plate.
• Set the rated stirring speed and begin.
• Observe the stirring bar and LCD display.
• Set the rated temperature and start heating.
• Observe the real temperature on LCD display.
• Stop the heating and stirring functions.
  If these operations above are normal, the device is ready to operate. If these operations are not normal, the device may be damaged during transportation, please contact manufacturer for technical support.

Initialization

Initializing sequence

• Turn on instrument by the power switch.
• The“Heat”and“Stir”LEDs and the LCD display flash about 3 times.
• LCD displays the work plate, safe temperature limit in “SAFE xxx℃”.
• LCD displays residual heat warning“rES On/OFF”.
• LCD displays stirring bar breakaway monitoring“br On/OFF”.
• LCD displays the“Probe”characters in case of connecting with external temperature sensors.

Default settings

The following table is supplied with default settings:

Function

Heating

The device is controlled by digital temperature control technology, which has two separate safe circuits. The hotplate is kept at a constant temperature by a digital control circuit. The hotplate temperature can also be monitored from a separate, adjustable safe circuit. The two temperature sensors (PT1000) internal for temperature control are built into the hotplate. The single external PT1000 can monitor the temperature of sample.
If external temperature sensors needed, it must be plugged in before the device is switched ON.

• Ensure the external temperature sensor connect firmly before heating.
• Set the temperature via turning the temperature control knob slowly to the ideal value.
• When the heating function is switched on, the LED “Heat”will light up and the LCD will display the real temperature.
• The rated temperature will be displayed on the right-hand side of the LCD as well as Temp and℃ characters.
• The heating function is switched on or off by pushing heating knob.

Instrument is turned on for the setting zone temperature setting when the last shutdown temperature, the common  case, set the heating temperature display the actual temperature may have the following differences:.

• Hotplate center and outer edge.
• The sample container and the container.

In order to ensure the accuracy of the temperature inside the container, please use the external temperature sensor PT1000.

Working with external temperature sensor

The external temperature sensor PT1000 is the Manufacture’s standard accessory. If the sensor is not plugged in,“Probe”will flash. If plugged in,“Probe” will be shown on the digital display to indicate the sensor is operating. The setting value of external temperature sensors and actual temperature are displayed. Safe circuit controls hotplate temperature.
Comparing with the temperature control of the hotplate, the external temperature sensor can control the medium’s temperature more precisely.

Warning Do not insert or remove sensor while heating.

Residual heat warning (Hot)

In order to prevent the risk of burns from a hotplate, digital hotplate model has a residual heat warning function. When the heating function is switched off and the hotplate temperature is still above 50℃,“Hot”will flash to warn that there is a hazard of burns from the hotplate (Figure 6).When the hotplate temperature drops to below 50℃, the unit will automatically switch off. If users want to turn off the LCD immediately, just pull out the plug directly. When the plug is pulled out, the residual heat warning function can not be run. 

Setting the safety temperature 

The safety temperature can be set as follows:

• Adjust the temperature setting key to set the safety temperature.

Stirring

The function“stirring”is switched on or off via rotating stirring knob. The speed is set on the knob (100 to 1500 rpm in steps of 10 rpm ). When both of function heating and stirring are switched on and those above operations are done, the LCD will shift to the speed value and come back to the temperature value in about 5 seconds.

Remote control

The unit can be controlled from an external PC (using the dedicated software) via the RS232 C serial interface fitted to the unit. Data communication from laboratory instrument to computer is only possible on demand of the computer.

• The functions of the interface lines between laboratory instrument and automation system are selected from the specified signals of the EIA-standard RS232C, corresponding with DIN66020 Part 1. The allotment of the bushing can be taken from Figure 7.
• Transmission method: Asynchronous signal transmission in start-stop-operation.
• Mode of transmission:Fully Duplex.1start bit; 7 character bits; 1stop bit.
• Transmission speed: 9600 bit/s.
• Start remote control knob LED display “Remote”.

Note:
Forbid to insert or remove the RS232C communication line when switch on!

Safety Instructions

Warning!

• Read the operating instructions carefully before use.
• Ensure that only trained staff works with the instrument.

Risk of burn!

• Caution when touch the housing parts and the hotplate which can reach temperature of 550℃.
• Pay attention to the residual heat after switching off.

Protective ground contact!

• Make sure that socket must be grounded (protective ground contact) before use.
• When working wear personal safety guards to avoid the risk from:
  • Splashing and evaporation of liquids
  • Release of toxic or combustible gases
• Set up the instrument in a spacious area on a stable, clean, non-slip, dry and fireproof surface. Do not operate the instrument in explosive atmospheres, with hazardous substances or under water.
• Gradually increase the speed, reduce the speed if :
  • Stirring bar breaks away due to high speed
  • The instrument is not running smoothly, or container moves on the base plate
• Temperature must always be set to at least 50℃ lower than the fire point of the media used.
• Be aware of hazards due to:
  • Flammable materials or media with a low boiling temperature
  • Overfilling of media
  • Unsafe container
• Process pathogenic materials only in closed vessels.
• Check the instrument and accessories prior to each use. Do not use damaged components. Safe operation is only guaranteed with the accessories described in the“Accessories”chapter. Accessories must be securely attached to the device and can not come off by themselves. Always disconnect the plug before fitting accessories.
• Ensure that the external temperature sensor is inserted in the media to a depth of at least 20 mm.
• When using metal vessels, do not place the temperature sensors on the bottom of the vessel. This can cause excessively high temperatures to be measured especially in media with poor conductivity.
• The tip of the measuring sensor must be at least 5 mm from vessel bottom; a distance of 10 mm is ideal.
• The instrument can only be disconnected from the main power supply by pulling out the main or the connector plug.
• The voltage stated on the label must correspond to the main power supply.
• Ensure that the main power supply cable does not touch the hotplate. Do not cover the device.
• The instrument may only be opened by experts.
• Keep away from high magnetic field.

Maintenance and Cleaning

• Proper maintenance can keep instruments working properly and lengthen its lifetime.
• Do not spray cleanser into the instrument when cleaning.
• Unplug the power line when cleaning.
• Only use recommended cleansers:

• Wear the proper protective gloves during cleaning of the instrument.
• Before using another method for cleaning or decontamination, the user must ascertain with the manufacturer that this method will not harm the instrument.
• Send in the case of service the instrument back in the packaging carton. Storage packing is not sufficient for the back dispatch. Use additionally a suitable transportation packing.
• The enamel makes the hotplate easier to care for and more resistant to acids and bases. Because of it, however, the hotplate is also more susceptible to extreme fluctuations in temperature and the force of impact. This can result in cracks forming or the coating flaking off.

Warning！
Cut off power when maintenance and cleaning.
