Monark Exercise AB

Monark has 100 years’ experience of bicycle production. The Monark tradition has yielded know-how, experience, and a real feel for the product and quality. Since the early 1900s, Monark’s cycles have been living proof of precision, reliability, strength and service. Those are the reasons why we are now the world leader in cycle ergometers and the market leader in Scandinavia in transport cycles.

We manufacture, develop and market ergometers and exercise bikes, transport bikes and specialized bicycles. Our largest customer groups are within health care, sports medicine, public authorities, industry and postal services.

LC6 / LC7

Thank you for choosing a test cycle from Monark!

Ideal position is important for performance to reach its maximum. LC6/LC7 has a brand new frame that is adjustable in all directions. The frame also allows the Q-factor to be reduced, which further increases the possibilities for a perfect performance. The new setting options, along with an upgraded braking system, make Monark's renowned bike even better.

LC6/LC7 gives the conditions; the rest is up to the rider.

In today's society we are used to customizing our machines and tools for our own needs. The same applies to LC6/LC7. Through intelligent solutions parts can be customized according to user requirements. LC6/LC7 is also prepared for additional equipment, channels behind the covers make it easy to install different equipment for different needs. LC6/LC7 is a great bike as it is, with additional equipment, it can be even better.

Force is a strong word which brings many associations. For us, force is interesting when it can be measured and calibrated. For a brake-force to be correct, regardless of the system, it must be calibrated and controlled. On LC6/LC7 the brake system and calibration have been updated so that it is safer and more accurate. It is also quicker to adjust and has more options in that it is speed-independent, but can be switched into constant braking force as an alternative.

Monark has always been known for the bikes measurement accuracy, now it's even better.

Cycle adjustments

Seat height should be adjusted to a comfortable position. The appropriate height is to have the knee slightly bent when the sole of the foot is centred over the pedal axle with the pedal in the bottom position. When adjusting the saddle height and vertical position, loosen the respective locking handles. See Fig: Overview at page 7.

The handlebar setting should be in a comfortable position when cycling. During longer exercise sessions it is recommended to occasionally change handlebar position. The handlebar can be adjusted both horizontally and vertically. This is done by loosening the respective locking handles. See Fig: Overview at page 7.

NOTE! Be sure that the stem and seat post are inserted to at least 100 mm in the frame. This is marked with “MAX” on the stem.

Initial operation

LC6 / LC7 is mechanically calibrated in the factory. The user may wish to verify this by performing the mechanical calibration of the pendulum weight. See ”Electronic calibration”.

Apply power to the test bike by ﬁrst connecting the cable from the power adaptor to the test bike at the power connector (3) at the right side of the bike, see Fig: Front cover right. Then plug the power adaptor into the wall outlet. Turn on the power switch (2) and a green LED (1) lights up.

The cable from the power adaptor can be locked with the clamp (4) which is placed below the power connection.

Perform the electrical calibration as speciﬁed in section "Calibration Electronics”. Test by pedalling the bike. If the bike is working properly, it is ready for use.

Power on crank or ywheel

Monark bikes measure the effect of the ﬂywheel, so it will be a friction of 6-8% if you measure the impact of the pedals (measure the effect of the crankshaft, the difference is 4-5 %). These percentages will be primarily due to friction in the chain, pedals and bearings.

LC6 / LC7 is designed for ﬁtness tests and is set for power measurements on the ﬂywheel. The bike can be set to work with effect in the pedals / crankshaft (the cycle constant).

Measured quantities

The following units are normally used. Where multiple units are speciﬁed, the user can select, see the software documentation.

Control of the bike

LC6 / LC7 is built on a solid framework, a large well-balanced ﬂywheel, a brake belt and a pendulum that measures the braking force. The pedals operate around the brake wheel via a chain, while a stretch mechanism tightens the brake belt to regulate the braking force to affect the ﬂywheel. This brake force is given directly by the pendulum against the scale on the right side of the bike.

The computer system consists of a main unit (built in the bike) and a control unit (integrated computer on the bike, PC, terminal or other external equipment). The main unit reads pedal speed and braking force and to determine the test subject's heart rate by a chest belt, where applicable. In addition, the main unit activates an actuator, which adjusts the brake belt tension that regulates the braking force. This brake force is varied automatically in relation to changes in pedal speed, so that a constant power is maintained The bike is as default rpm-independent.

For information about how respective control units works, see respective sections.

The bike can be controlled externally by PC, terminal or other external equipment.

Here are instructions for connection and options for connection to external devices. If advanced technical documentation / data protocol for system builders or similar are required, contact Monark Exercise AB.

The control is performed over a serial line using ANSI/ ISO/ASCII format commands. Connector, a 9-pin D-Sub (male) located below the RPM meter, see Fig: Connector, is compatible with the RS232 standard.

The bike need not be switched off when connecting external components, but it is recommended to prevent transmission of incorrect data between devices over the connection.

Be careful when connecting different types of external equipment to prevent ﬂash-over and subsequent injury. The user must ensure that the correct cables are used, otherwise you risk serious injury or equipment damage.

Keys and functions

MODE key

Use MODE key to shift between the functions to set TIME and TOTAL COUNT.

SET key

Pressing this key will make it possible to set TIME and TOTAL COUNT. If you hold down this key for two seconds you can advance the function value at a faster rate.

Programming exercise time:

Push the MODE key until TIME ﬂashes. Then use SET to set the desired time. Each press of SET will advance time by one minute. When the pedals are rotated the countdown of time will start automatically and count down to 0:00 and a beep will be heard for ﬁve seconds.

Programming TOTAL COUNT:

Push the MODE key until TOTAL COUNT ﬂashes. Then use SET to set the desired value. Each press of the SET will increase the value by 10. When the pedals are rotated the countdown of number of turns automatically start and count down to 0 and a beep will be heard for ﬁve seconds.

RESET key

The RESET key will clear the values for TIME and TOTAL COUNT individually.

NOTE!

Display will return to normal when not pressed • any key for ﬁve seconds, or trainer is not used.

The meter starts automatically when a key is • pushed, or if the bike is used and the meter gets an indication of pedal movement.

Auto shut off function when not pressed any key • or device not used for four minutes.
