Our Jolly Jogger control offers a simple, versatile and comprehensive solution in treadmill applications. With the only other external item required to realize a functioning treadmill, the variable speed AC or DC drive, the Jolly Jogger monitors and controls all treadmill activity for a safe and vitalizing experience.

The Jolly Jogger treadmill controller, front and rear view.

The Jolly Jogger integrates all the functions expected in a treadmill application:

• Drives the treadmill variable speed AC or DC motor drive,
• Directly controls the slope motor rise and lower movements,
• Estimates or uses the available encoder feedback in measuring treadmill speed and travelled distance,
• Estimates or uses the available slope encoder/potentiometer feedback in measuring slope angle,
• Incorporates all user safety and operational safeguard procedures, and
• Features a simple, "clean" and attractive user interface with large LED displays and tactile switches.

All aspects of Jolly Jogger operation are set and controlled by configuration parameters kept in non-volatile memory. The parameters are accessible/set via the front panel display and switches or the board's serial port and the provided monitoring/setup software.

The controller is designed for 50-60 Hz supply lines of 115 and 230 VAC and with the following characterizing features:

• The speed controller (typically an AC inverter or DC drive) is driven with a 0-10 VDC control signal and an enabling or direction setting optotransistor output which can be connected to both, PNP (active-high, current source) and NPN (active-low, current sink) inputs. Practically any inverter/drive in the market can be used,
• The raising or lowering mechanism is controlled by independent 8 A relays and, as such, can be driven with any, DC or AC, voltage,
• The available I/O interface signals are the up/down terminal switch inputs, the speed/slope encoder inputs and the drive enable output. They are all standard 24 VDC types and optoisolated from the internal logic,
• In the usual case where some of the limit switch or encoder inputs are not used (typically the limit ones), they can double as a general enable by connecting them to a safety switch,
• The anodized alluminium front panel is 2 mm thick and sized 30 x 20 cm (11.8 x 7.9 in). The controller PCB is fixed at its back and with its 249 x 152 mm (9.8 x 6 in) dimensions allows for the assembly to "drop" into a suitably sized hole and be fastened with countersunk screws at the front.

The controller can be programmed, configured and monitored by computer using the USB/TTL interface and the provided jolly_jogger_jobs software, downloaded from here (765K, zip archive).

The controller is also offered in retrofit form for popular, used third party treadmills. Current offerings include Technogym© and Precor© platforms and we are always seeking market/customer input in expanding the line.
