Adjustability

The ergometer is adjustable to test subjects of all sizes and ages.

• The height of the saddle can be adjusted by tilting the handle on the back underneath the

saddle

• The height of the handlebars can be adjusted by loosening the screw knob in front of the

ergometer.

Moving the ergometer

The ergometer can be moved by turning it over to the right (appr. 30▼) when you are in front
of the handlebar. A wheel in the middle of the ergometer drops out. You can now drive the
ergometer to its location. Turn it over to the left (appr. 30▼) and the wheel in the middle will
fold in. The ergometer is ready for use.

Instructions for installing the Corival ergometer

1. Place the ergometer in the location where it will be used.

2. Check (at your supplier) whether the voltage set for the ergometer is set correct.

3. Connect the power cord first to the socket of the ergometer and then connect it to the
line voltage.

4. Switch the power switch on. The indicator lamp in the switch lights up.

If the following initialisation screen with the software version will appear for a few seconds,
the ergometer is ready for use.

1.1 Manual control quick start

If the Corival is switched on, the default startup menu is the entrance to the MAIN MENU.
Press the confirmation button ( ) to enter the main menu. Select with the arrow keys ▲♥ the
MANUAL MODE. Press ( ) and you will see the following screen:

With the ▲♥ keys the workload can be in- or decreased. The workload will rise with 25
watt/sec when the rpm is above 30. Keeping the ( ) pressed for a few seconds allows you to go
up one or more menu levels.

During cycling, the display shows the following information:

• the top line shows 1 or more ergometry parameters.

• the bottom right corner shows the current control mode.

• at the bottom left position the selected adjustable parameter is shown.

1.2 Analog external control

Execute the following steps to control the Corival externally using the analog in-/output:

1. Connect the external controling device (e.g. ECG system) with a correct cable to the

analog i/o port.

2. Start the ergometer and go in the main menu to ANALOG.

3. Now the ergometer can be controlled by an external device with an analog signal.

1.3 Terminal  digital external control via RS232

For digital external control using the RS232 serial port execute the following steps for the
basic Corival:

1. Connect the Corival to the external control device (i.e. ECG system, PC) using a

correct RS232 cable

2. Switch on the ergometer and select the menu TERMINAL on the display.

3. Be sure that the correct protocol has been selected under the menu SYSTEM

PARAMETERS / SETTINGS / RS232 PROTOCOL

For a list of available protocols and ECG system, we refer to the user guide or your local
dealer. If you usually control your ergometer from an ECG system in the TERMINAL
MODE, you can set this mode as default startup menu. The Corival is now ready for digital
external control. Another option to control the ergometer from a pc is with the Lode
Ergometry Manager (LEM, article 92890X) software. This uses the Lode 38k4 protocol.

3 System parameter

In the System Parameters different specific ergometer settings can be carried out.

3.1 Set display

This function allows you to adjust the parameters which can be read out on the display during
exercising. If more then 2 are set to ON they are shown in groups of 2 scrolling. Choosing
default allows you to go to factory settings for the display parameters.
Press the ( ) button to go to the next parameter and switching the actual parameter ON/OFF is
done with ▲♥ keys.

3.1.1 Power

Power indication in watts can be switched ON or OFF using the ▲♥ keys. The power
displayed is the actual power of the brake. When rpm drops below 25 rpm the load is removed
at once, because the pedal torque becomes very high. Load is put on the brake when rpm is
greater or equal to 30 rpm.

3.1.2 RPM

Swith ON of OFF the Cadence readout in Revolutions per minute. The rpm can always be
read out by the LED bargraph on top of the display independent of this adjustment.

3.1.3 Heartrate

Switch ON or OFF the Heartrate indication in beats per minute. The α symbol is used in the
display.

3.1.4 Torque

Switch ON or OFF the Torque in the readout. The Torque is displayed in Newtonmeter.

3.1.5 Timer

Switches the Timer ON or OFF in the readout. The timer is shown in the display as: → =
mm:ss. The timer starts when you enter manual, terminal or analog mode and the rpm

increases above 30. The timer is reset when one of these modes is left.

3.1.6 Distance

Switches the distance ON or OFF. The distance is shown in the display as: ▼ = 99,9 km ,
expressing the distance in km. A fictive formula is used (see user guide), holding only for
average cycle conditions and it should not be used for diagnostic purposes.

3.2 Set P-slope

The load regulation steepness is set by this parameter to the default norm-value of 25 watt/sec
or to unlimited.

3.3 Set mode

Set mode is used to define which parameter (like workload, torque, heart rate and linear
constant alpha) has to be adjusted during exercising in MANUAL mode with▲♥ keys

9

Operator Manual Corival

3.3.1 Hyperbolic

Hyperbolic mode means that the workload P can be adjusted in watt. The workload is kept
constant independent of rpm.

3.3.2 HR controlled

Heart rate can be adjusted and the workload is regulated until the adjusted heart rate is
reached. This means when heart rate increases above the adjusted level load is decreased and
the other way around.

3.3.3 Linear

In linear mode the workload P is coupled with rpm using the following formula:

P [W] = π* (n [min-1] )

The linear coupling constant π is the adjustable parameter in this case.

2

3.3.4 Fixed Torque

In Fixed Torque mode the workload is regulated such that the torque is kept at a set fixed
value, according the formula:

T [Nm] = (P*60) / ( 2 * Ω * n [min-1])

3.4 Settings

Under settings all device specific and interface adjustments can be made. It concerns to all
those items not related directly to ergometry.

3.4.1 Default Startmenu

Normally your ergometer starts in the main menu. But you can modify this menu to your own
desired settings. This is convenient when your ergometer is used often in the same setting,
The following menus can be selected as startmenu: MAIN MENU; MANUAL; TERMINAL;
ANALOG At the next startup of your ergometer the selected menu will be activated.

3.4.2 Keyboard On/Off

If you do not want to interrupt a training or you do not want the test subject to interrupt the
training by pressing a key accidentally, the possibility is offered to disable the keyboard
Now you wonder how to get back the control to the keyboard. Act as follows:
Switch off the ergometer
Switch it on again while keeping the ( ) button pressed. Now you have back the control. Go to
SYSTEM PARAMETERS / KEYBOARD ON/OFF and set it to ON.
At the next startup of the ergometer the keyboard is enabled again.

3.4.3 Test Functions

For servicing and calibration of the device a number of diagnostic tools is available in the
software. They are hidden under Test functions. You need a safety code to enter the
TESTFUNCTIONS.

3.4.4 P In/Out Analog

The ergometer can be controlled by an external device which has an analog output only. This
is done using the ANALOG mode. With P In/out Analog the analog scaling can be adjusted: 1
V analog in can correspond with a workload of 100 W / 200 W / 500 W.
