Commissioning

Mounting the support rod
The supplied support rod is used to fit the stirrer on a stand or a wall grid. Insert the support rod in the receiving hole at the back of the stirrer so that the screwed-in grub screw presses on the flat area of the support rod and thus fixes it  securely

• Turn the grub screw clockwise to fix the support rod.
  • Tighten the grub screw by hand only and with the help of the hex wrench supplied.
  • Make sure that you do not overtighten the grub screw, as this damages the thread.
• Turn the grub screw counterclockwise to loosen and dismantle the support rod.
• Then fix the fitted support rod to an adequately load-bearing wall grid or a stand with the help of suitable clamps (for suitable accessories, see www.heidolph.com).

Set up the device
The described overhead stirrers can be mounted on a stand or on a wall grid. Any necessary mounting materials are available as accessories, see www.heidolph.com. Follow the safety instructions below:

WARNING
Risk of injury, risk of damage to property due to fall or tilting If assembled improperly, the device can also fall or tip over when unloaded!

• If the overhead stirrer is mounted on a wall grid, ensure that the wall grid and all mounting elements have sufficient self-protection and load capacity!
• When mounting the overhead stirrer on a stand, make sure that the setup is sufficiently stable.
  • The stand may only be set up on a stable surface.
  • When mounting on a stand, follow the specific setup instructions for the stand.
  • Always align the overhead stirrer so that the chuck vertically faces the notional centerline between the long stand base bars, see following figure:
  • After assembly of the overhead stirrer, check all screw connections / clamping screws for tight fit.

Chuck for stirrer tools
WARNING: Risk of injury due to rotating parts

• Before mounting/dismantling the chuck, switch off the device and disconnect it from the power supply to prevent unexpected starting-up of the device!
  • The chuck is fixed on the stirrer shaft by a grub screw so that it cannot rotate:

Inserting and locking the chuck

• Push the chuck onto the stirrer shaft so that the screwed-in grub screw engages in the assembly hole of the stirrer shaft and the chuck can thus be fixed securely (above figure, right).
• Use the hex wrench supplied to turn the grub screw clockwise, in order to fix the chuck.
  • Tighten the grub screw by hand only and with the help of the hex wrench supplied.
  • Make sure that you do not overtighten the grub screw, as this damages the thread.

Clamping/removing stirrer tools
WARNING: Risk of injury due to rotating parts

• If necessary, stop the rotational movement and before clamping/ removing stirrer tools, switch off the device to prevent it from starting up unexpectedly! Proceed as follows to clamp/remove stirrer tools:
• Turn the chuck clockwise to open it until the required stirrer tool can be inserted.
• Insert the stirrer tool into the chuck. Make sure that the working height is as required!
• Hold the stirrer tool as close as possible to the middle, and close the chuck by carefully turning it counterclockwise until the stirrer tool is tightly clamped.
  • The quick-action chuck can be overturned by excessive force applied to the opening! In this case, the quick-action chuck can no longer be closed normally and a latching noise can be heard on turning it in the closing direction.
  • Remedial action: Turn the quick-action chuck again in the opening direction, beyond the latching point. The quick-action chuck can then be operated normally again.

Power supply
The device has an appliance outlet with locking system for the power supply. A suitable three-pole power supply cord is included in the scope of delivery.

DANGER: Electric shock, damage to property, loss of production

• The device may only be supplied with the required line voltage via a grounded power socket. Power cords without a locking system can become loose during operation due to vibrations. In the event of an uncontrolled shutdown of the stirrer tool, there is a risk of production downtime and / or property damage, e.g. due to an uncontrolled restart!
• For reasons of operational safety, only use the supplied power supply cord with locking system!

Connect the power supply cord

• Before connecting the power supply cord, make sure that the main switch of the device is in the OFF position (see following section “Switching the device on/off” on page 44).

• Press in the locking lever on the cable coupling and disconnect the power supply cord from the IEC appliance plug on the back of the device.

Switching the device on/off

To switch the device on and off, use the main switch on the front of the device below the control panel::

Automatic restart
This function can be used to set the device so that the stirrer is restarted automatically after being switched off or after a power outage, and the speed is run up to the last set value.

CAUTION

• Always activate or deactivate the automatic restart function as required before the actual process start!
• Pay attention to the safety symbols on the device for signaling the functional status for all process sequences.
• If the automatic restart function is active, secure the device with an information sign if necessary.

Proceed as follows to activate/deactivate the automatic restart function:

• Switch on the device and use the speed controller to set the rotational speed value to [213 rpm]: Value has white background field.
• Wait for approx. six (6) seconds until the value is accepted: Value is displayed without background field.
• Then use the speed controller to set the rotational speed values in chronological order to [214 rpm], [215 rpm], [216 rpm] and [217 rpm] and wait each time until the value is accepted.
• As soon as the last value [217 rpm] has been accepted, the status change is completed:
  • On activating the function, the [restart on] notice is displayed briefly.
  • In operation with active automatic restart, a small white caution symbol is shown continuously at the top edge of the screen.
  • On deactivating the function, the [restart off] notice is displayed briefly.
  • As soon as the automatic restart function is deactivated, the warning symbol at the top edge of the screen goes out.
  • On restarting after a power interruption, a [Rotation] warning triangle appears on the display briefly, the white caution symbol at the top edge of the screen then flashes until the rotational movement is stopped normally.
  • A power interruption that occurs during unsupervised operation can be identified by this flashing function.

Setting the rotation speed
The settable speed range lies between 20 – 2,000 rpm. To set the required speed, do the following:

• Turn the speed controller clockwise to increase the (rotational) speed.
• Turn the speed controller counterclockwise to reduce the (rotational) speed.
• When setting the required speed, monitor the set value on the display:
  • In the [Rotation off] state the display value has a white background when changed. After six seconds, the new set value is adopted automatically and the background field is hidden.
  • In the [Rotation on] state, the rotation speed is adjusted immediately according to the new setting.
• The actual display is shown on the display as the actual value, see also section “Overview of the Hei-TORQUE Core overhead stirrer” on page 39.

Starting/stopping rotation
Start and stop the rotational movement by pressing the speed controller.
WARNING: Risk of injury due to glass break and leaking medium

• Select the diameter of the laboratory vessel so that the stirrer tool turns inside the vessel without touching it.
• After clamping the stirrer tool and before the process starts, check the stirrer tool and the chuck for smooth running.
• Never start up stirrer tools or chucks that have an unbalance, and replace them immediately.

Risk of injury on rotating parts

• Never grip turning parts.
• Always wear close-fitting clothing when working with the device.
• Do not wear any accessories such as ties, scarves, shawls, pieces of jewelry, etc. when working with the device.
• When working with the device, tie back long hair or wear a cap or hair net.

Property damage, loss of production

• Follow the specific safety instructions for the substances to be processed (refer to the safety data sheets if applicable).
• Always wear the required individual personal protective equipment (PPE).

Overload protection
The device is equipped with an overload protection function: The performance indicator on the display (see section “Overview of the Hei-TORQUE Core overhead stirrer” on page 39) visualizes the effective loading in the form of a progress bar. In case of an overload (e.g. if speed is too high in highly viscous substances), the outermost right-hand segment of the performance indicator flashes. In this case, reduce the rotation speed until the performance indicator returns to normal mode. In the event of persistent overload and in case of a blockage, the rotational movement is stopped. In this state, two restart attempts are started automatically. If the load does not reduce sufficiently, the rotational movement is switched off. In this case, check the stirrer tool and the device for blockages and adjust the rotation speed to the substance to be processed if necessary. The rotational movement can then be started again normally.

Timer function
The timer function can be used to preselect a required stirring duration. If the timer function is activated, the timer symbol appears on the left at the top of the display, see also section “Overview of the Hei-TORQUE Core overhead stirrer” on page 39.
Activate and set the timer as follows:

• Make sure that the rotational movement has stopped. Otherwise, the timer cannot be activated and set.
• Press the [Timer] button on the front of the device:
  • The [Timer] button lights up.
  • The [Timer] Settings menu opens.
• Use the speed controller to select the [Timer set] menu option.
• Press the speed controller to confirm the selection.
• Select the [hh], [mm] and [ss] options one after the other, and set a required stirring duration in hours, minutes and seconds (from one second up to 99 hours, 59 minutes and 59 seconds).
  • Confirm each individual value by pressing the speed controller.
  • Turn the speed controller to mark (select) and adjust the next value.
  • After confirming the value for seconds, the [ON] option is selected automatically: Press the speed controller to confirm and activate the timer.
• The timer is started on starting the rotational movement.
  • For physical reasons, the maximum speed can only be reached after a certain delay. This factor must be taken into consideration, in particular if, in timer mode, high speeds are to be reached in a very short time.
  • The effective delay until the required rotation speed is reached depends on the prevailing ambient conditions, on the stirrer tool used, and the substance processed.
• If the rotational movement is stopped before the timer has expired, it is stopped and continues running when the rotational movement restarts.
• If the timer time expires normally (no interruption due to manual stopping of the rotational movement), the rotational movement is stopped automatically and the timer is reset to the set time, e.g. 60 s.
• If the rotational movement is restarted after the timer expired normally, the timer is restarted with the set time.

While the timer is running, the remaining time is shown on the display to the nearest second. At the same time, the timer symbol appears on the left at the top of the screen.  To deactivate the timer, it must be switched to [OFF] via theSettings menu.

Fast mode
With this function, the device can be set for a certain time to the maximum speed of 2,000 rpm with the press of a button:

• Press the [Fast mode] button on the front of the device and keep it pressed:
  • The rotation speed is increased to and kept at 2,000 rpm.
• Let go of the [Fast mode] button to reduce the rotation speed back to the previously set value.
  • The fast mode function can be activated at any time and independently of the operating state. I.e., the stirrer tool starts, from a standstill if applicable, as soon as the [Fast mode] button is pressed.
  • Fast mode phases are not recorded in timer mode.
