GENERAL INFORMATION

Unpack your item carefully.
Inspect for damage and report such damage or missing parts to your supplier right away.
Read your Instruction Manual carefully. Take time to save time when working with your product.
Make sure that every user has read and understood the Instruction Manual.
Please store the Instruction Manual in a place easily accessible to every user.
IF ALL ELSE FAILS, READ THESE INSTRUCTIONS !
A so-called EURO-plug (DIN 49441 CEE 7/VII 10/ 16 A 250 V) is standard on all of the products.
For the Continental US they feature a US-standard plug (NEMA Pub.No.WDI.1961 ASA C 73.1 .
1961 page 8 15A 125V).
For using the item in a country with deviating outlet / plug systems, we recommend to use approved adapters or to have an electrician replace the standard plug with one suiting your needs.
As shipped, the item features a protective ground wire. When replacing the original plug, make sure to reconnect this protective ground wire in the new plug !

SAFETY INFORMATION

Please comply with all safety and accident-prevention regulations as in force for laboratory work!
Use extra care when working with flammable substances; refer to safety data sheets.
When connecting your item with your local power supply, please make sure your item is designed for your local voltage; go by the data plate on the item.
Turn your power switch OFF whenever the item is not used, or before disconnecting the plug.
Repair work is limited to technicians approved by Heidolph Instruments.
Use extra care when working in the vicinity of flammable and explosive substances. Motors are of non-sparking type, the item itself however is not explosion-proof.
Please connect your stirrer with a protective-ground outlet only.
Please strictly comply with current safety regulations for machines exposing rotating shafts.
Your item needs a solid stand.

SET-UP

1. Install stand
   make sure the indent (A) of the rod is in line with threaded pin (B). Install stand in hole (C) in the rear of the item. Secure (pull tight) threaded pin (Busing Allen key (D).

2. Install chuck
   make sure the indent (E) in the drive shaft is in line with threaded pin (F) in the chuck. Secure threaded pin (F) with Allen key (H) in your hardware bag.

3. Install stirrer on stand
   Install clamp (I) on stand (J).
   Now introduce stirrer attaching rod (K) into clamp (I).
   Adjust position and secure (pull tight) with two clamp screws (L).

4. Install stirring tool Introduce stirring tool (N) in chuck (G), put in place and secure with Thandle (M). Immersion depth of your stirring tool (N) is adjusted by displacing the tool in and out in the open (G) chuck (except RZR 2102 control Z).
   Refer to arrow mark.

5. Install flexible coupling shaft (P/N 509-03000-00)
   Hold the flexible coupling shaft (O) in the chuck (G) by its metallic stud (P) and secure with T-handle. At this point introduce stirring tool’s (N) shaft end in collet (Q) and pull tight (CW turn).
   When using the flexible coupling shaft make sure to install an adequate run- out protection, e.g. our enclosure (P/N 509-09000-00)

6. Install shaft guard (P/N 509-08000-00)
   A shaft guard (R) is available as an extra safety protection feature.
   This guard tube is held by 2 ea. screws (S) located at the top of the stirrer chuck.
   This guard, attached to the stirrer housing, is used to protect the user from being hurt by the fast-spinning shaft.

OPERATION AND CONTROLS

1 Turn item ON

Set speed control (4) to its extreme left position (CCW). When turning the power switch (1) ON, the following info will appear in the display (5) followed by speed and torque; at standstill, „rpm“ in line 1 will change between rpm and OFF, which means the item is ready to go.
2 Speed setting
2.1 RZR 2051 control, RZR 2052 control, RZR 2102 control and RZR 2102 control Z
At standstill of the item, speed may be preselected with the rotary speed control (4). RZR 2051 control speed range includes 50 – 2000 rpm, the RZR 2051 control features 30 – 1000, the RZR 2102 control features 12 – 400 and 60 – 2000 in 2 ranges and the RZR 2102 control Z features 4 – 108 and 17 – 540 in 2 ranges. Speed selected appears in line 1 of display (5).
Hitting the ON/OFF key (2), the stirrer is going to speed-up to the level selected, after a short pause.
Acceleration is smooth, thus preventing the medium from splashing.
Whenever changing speed with rotary control (4) while running, display is going to show nominal speed.
For convenience, nominal speed is displayed with the “ „ prefix. This prefix disappears, when actual speed is displayed !
2.2 RZR 2102 control and RZR 2102 control Z
This stirrer features two different speed ranges:
RZR 2102 control:

Transmission ratio is obtained with the RANGE key (8). Speed range actually selected is displayed by an LED (9 or 10).
At standstill, speed may be selected with the speed control (4), within both speed ranges (I or II). In standby mode, the display (5) shows the speed value (set-mode).
Change speed range, RZR 2102 control and RZR 2102 control Z
Select your speed range with the RANGE key (8). LEDs (9) and (10) confirm the range selected. When switching from range I to II, stirring speed is multiplied by factor five.
Note:
To avoid splashes (in particular when open containers are used), speed range cannot be changed unless the item has been turned OFF before.
How to proceed:

• turn stirrer OFF with ON/OFF key (2)
• turn speed control (4) to its extreme left position (CCW) (= low speed)
• change speed with key (8)
•  turn item ON with ON/OFF key (2)
• set speed with speed control (4)
• speed appears in display (5), line 1

You may change from range II to range I at any time without any extra precautions necessary.

3. Torque display
Both stirrers feature a digital display (5) for stirring torque (line 2). Before measuring, you need to „zero“ your torque display ( = 0,0 Ncm), to benefit of the highest accuracy available from this system (refer to stipulations below). This is of particular importance, when changing stirrer speed.
How to „zero“ the torque display:

• allow the stirrer to warm at max. speed for about 20 minutes.
• define speed needed for your particular job
• select standby mode with the ON/OFF key (2)
• lift stirring tool with stirrer out of the medium, or remove stirring tool from chuck (refer to para. 4 „setup“). This way, the motor won’t be able to build up any torque while spinning.
• turn item ON with ON/OFF key (2)
• with the motor running, hit the „cal“ key (7), display (5) is going to change to „0,0“ Ncm in line 2
• turn the item OFF, re-install stirring tool in (refer to para. 4 „set-up“), or immerse your system in the medium again
• at this point you have an accurate torque reading

4. Interfaces
4.1 Interface connection
Turn power switch (1) to OFF before attempting to connect an interface. To connect your interface, you will need an interface cable with SUBHDD 15 connector which fits the socket (11) located in the item’s rear panel.
For more information about wiring order, refer to „analog interface and serial RS 232 interface“ diagram.
Only connect but the wires shown to avoid malfunction of your interface

Remote control allows ON/OFF mode of the stirrer (same as On/Off key)
5. Protective equipment
5.1 Overload LED
The stirrer features and extra overload LED (6) that will light in an overload situation. To get higher torque out of the item, overload operation is acceptable for a short period of time. After extended overload operation, a built-in thermal circuit breaker will disconnect the item automatically.
the overload LED (6) must not light during continuous operation; the item will be cut-off automatically after a short time!
5.2. Thermal overload protection
The stirrer features built-in overheat protection. If the item is getting too hot, either by overload (refer to 5.1) or high ambient temperatures, it will be disconnected automatically. The following error prompt appears in the display (5): Allow item to cool-off. As soon as temperature drops to an acceptable level, display (5) will read: Hitting the ON/OFF key (2), the item will return to normal operation, running at speed set.
5.3. Mechanical overload protection
In case of an overload situation including excessive torque (refer to torque graph under “Specifications”), or by stuck stirrer shaft, the stirrer is going to disconnect automatically.
Display (5) reads:

After 90 seconds, display (5) reads: When having fixed the problem, hit ON/OFF key (2) for re-start. Item will return to normal operation, running at speed set.
