Maintenance

Danger!
It is very important that you read and understand this section before operating the hose reel! Failure to follow the procedures and
cautions in this manual could lead to injury or possible death!
Precautions
Electric shock will result in death or serious injury.
•
The user is responsible for conforming to all applicable code requirements with respect to grounding all equipment.
•
Many parts in this drive controller, including printed wiring boards, operate at line voltage. DO NOT TOUCH. Use only electrically
insulated tools.
•
DO NOT touch unshielded components or terminal strip screw connections with voltage present.
•
Install and close all covers before applying power or starting and stopping the hose reel.
•
Before servicing:
-Disconnect all power.
-Place a "DO NOT TURN ON" label on the drive controller disconnect.
-Lock the disconnect in the open position.
•
Disconnect all power including external control power that may be present servicing the drive controller. WAIT 15 MINUTES for the
DC bus capacitors to discharge. Then follow the DC bus voltage measurement procedure beginning on page 5 of the "ALTIVAR 11
Adjustable Speed Drive Controllers Start-up Guide" to verify that the DC voltage is less than 45 Vdc. The drive controller LEDs are
not accurate indicators of the absence of DC bus voltage.
Auto Resets
The drive controller is factory set and will reload its factory default settings each time the AC line is connected. It will also automatically
start when recovering from a series of different faults.
Manual Resets
ELECTRIC MOTOR
Gound Fault
If a fault occurs due to a prolonged overload, overvoltage, undervoltage or phase failure, the control must be manually restarted. The control
can be restarted by:
1) Disconnect AC power and wait for at least 30 seconds for drive controller to power down.
2) Reconnect the AC power. This will re-initiate the factory default settings.
