Treadmill Hardware Manual 1011-0002 v1.02
Run
When the treadmill belt mode is set to RUN, the treadmill belt is enabled to move, and the speed can be
continuously adjusted by the SPEED knob. The display will report the set speed and the mode indicator will be
a progress bar that grows from left to right. The odometer or duration will begin to count up or down.
Acceleration
When the treadmill belt mode is set to ACCELERATION, the treadmill belt is enabled to move and the belt
speed will begin to accelerate or decelerate from its current speed toward the end speed, at the acceleration
rate indicated on the bottom of the screen. The top line will report the actual belt speed and the mode
indicator will be a staircase that grows from left to right.
4.4.3 Intensity / Rate
Turning the INTENSITY knob adjusts the electric stimulus and the current stimulus settings will be displayed on
the bottom line of the LCD screen. The information will persist for two seconds and then return to display the
acceleration settings.
Likewise, pressing the RATE button will display the current stimulus settings (without changing the repetition
rate) and will persist for two seconds. While the stimulus settings are displayed, repeated presses of the RATE
button will select the next repetition rate in the order of: 1Hz, 2Hz, 3Hz, 1Hz, etc.
4.4.4 Motor Overload
The power supply for the motor is protected by a thermal resettable fuse. If the motor is mechanically
overloaded and/or demands excess power from the supply, then the thermal fuse will open. In this situation,
the motors speed will drop dramatically and the message
“
!!! OVERLOAD !!!
”
will be displayed.
Use the MODE button to set the treadmill belt mode to STOP. Then inspect the hardware for excessive
treadmill belt tension, moving parts rubbing against others, or bearing resistance in the rollers and pulleys.
After the thermal fuse cools down and re-closes, the message is removed. Use the MODE button to resume
normal operation.
4.5 Treadmill Stimulus Detection
The Treadmill Stimulus Detection should have its experiment parameters setup first. Then the animals should
be loaded into the treadmill and the stimulus intensity and repetition rate should be set. Next the experiment
is started on the Treadmill Stimulus Detection. Finally, the treadmill belt is set into motion.
The list of experiment parameters are as follows:
•
Mode
•
Session Number
•
Number of Active Channels
•
Yoked Stimulus
•
Number of Visits
•
Number of Stimuli
•
Number of Complete Exhaustions
