Troubleshooting can be supported with the tool of acoustic beeps:
see chapter 5.11 “Optional settings: User Options”
Check OP07 if acoustic heart rate signal is selected.
Option
Description
Explanation / Display
OP07
Activate: Acoustic heart rate signal
% indicates: OFF or ON
OFF: No acoustic heart rate signal
ON: Acoustic heart rate signal for every beat. This function is normally
used to control the regularity of the heart rate or to find reasons for
transmitting problems (such as mobile phones or computer monitors).
9.9 RS232 interface
The most common causes for problems with the RS232 interface are
N Wrong connection cable between the running machine and the periphery.
N Connection to the wrong COM port of the treadmill or the periphery.
N Another program, running on the external PC, is blocking the COM-port where the treadmill is connected.
N Technical defects of the connection cable or male/female connector.
N False setting of protocols/driver at running machine or periphery (ECG, PC, ergospirometry).
N False setting of COM port at periphery (ECG, PC, ergospirometry).
9.9.1 Troubleshooting and testing of the RS232 interface
N Loop-back test: For testing the RS232 of the running machine, a special RS232 test plug including testing
instruction is available from the manufacturer. Connect the plug to the RS232 port and adjust OP20: 10
N A blinking code will appear, and the instructions will tell you if input and output of the RS232 are working well.
N PC software h/p/cosmos para control
®
. If you install the software on an external PC, you can control the running
machine. If it works, you know the running machine, the RS232 interface connection cable and the RS232 interface
card of the PC are working well.

9.10 MCU control unit / circuit board, battery
In rare cases, after several years of use, malfunctions of the control unit are possible because of low battery power.
If the incorporated 3V 225mAh CR2032 battery (Lithium type) is low, all support for the real time clock, storing the date
and time, print out of date and time and the handling of service intervals may be disrupted.
In this case, contact the service department to change the battery of the control unit.
In case of replacement see picture for right positioning of the battery.
The MCU control unit also has a number of status LEDs which can assist in diagnosis.
When communicating with the h/p/cosmos headquarters during error search and
trouble shooting, the authorized technician should observe the indications on these
LEDs and report to the h/p/cosmos headquarters.
