The Speed Sentry P1 and P2 utilize PLC components that replace the Speed Sentry model 10.
All of the functions previously provided in the model 10 are covered in these models. Dynamic Braking has been added for use on all electric motor applications. This feature has been added to provide a more reliable automatic braking system. Proper functioning of the Speed Sentry depends on the proximity switch and the overspeed and underspeed set-point SETTINGS
“entered” in the display. Units have the proximity switch mounted on the brake plate and obtain the pulsed signal from holes in the face of the brake rotor. The proximity switch should be parallel with the rotor maintaining an air gap of between 0.56” to 0.69”.
DISPLAY MEMORY SETTINGS PROCEDURE
Upon initial power-up, the Display will perform a self-test procedure, which lasts about 10 seconds.
CHANGING SCREENS: All 11 Screens are accessible via the Right and Left Arrow Keys.
Right Arrow = Page Down, Left Arrow = Page Up.
CHANGING VALUES: Depressing the F1 key will cause the stored numerical value to flash.
Use of the Arrow Keys will change the settings:
LEFT ARROW - Increments by 100 (3rd digit, if applicable) RIGHT ARROW - Decrements by 100 (3rd digit, if applicable) UP ARROW - Increments by 1 (1st digit)
DOWN ARROW - Decrements by 1 (1st digit)
When desired value is reached, pressing the ENTER Key will download the value into memory.
Pressing the Right Arrow Key while any screen is displayed will advances to the next screen.
Pressing the Left Arrow Key while any screen is displayed will return to the 1st screen.

7.0 OPERATING ROTAFLEX
Starting the Rotaflex Pumping Unit for the first time:
Your Rotaflex Pumping Unit was erected and run at the factory. Necessary adjustments were made and the unit is in good working order. However, additional adjustments may be required after erecting the unit at the well site.
After assembling the unit and performing maintenance, perform each of the following steps before starting the unit for the first time.
1. Remove all tools or articles of obstruction from the foundation and around the unit.
2. Check to be certain that all safety guards and shields are properly installed.
3. Remove the wooden shipping blocks located at the back of the weightbox. The wooden shipping block is used to protect the back wheels from being flattened after prolong periods of the unit laying down.
4. Check for proper lubricant levels in the gear reducer and chain reservoir. The gear reducer has been pre-lubricated at the factory, but should be checked prior to operation.
The vented breather filter should replace the shipping plug at the top of the gear reducer prior to start-up. The chain should be lubricated with 40 gallons of chain lubrication oil.
For more information, please refer to the LUBRICATION section.
5. Check that the prime mover is properly installed and mounting bolts are properly tightened.
6. Check that belts are aligned and properly tensioned and belt guard is in place.
7. Remove all safety stops and disengage the manual brake.
8. Make the first stroke as slow as possible to properly check the clearance between the belt guards, railings and any safety structure installed around the Rotaflex Pumping Unit. Be sure the polished rod and the downhole pump have clearance on the down stroke and upstroke.
WARNING: To prevent personal injury, stay clear of any moving parts!
7.1 COUNTERBALANCE ADJUSTMENT
Efficient operation, minimum torque loading and maximum life of a pumping unit are all a result of proper counterbalance. The auxiliary counter weight is supplied in properly dimensioned metal blocks of varying thickness. To calculate the weight of the auxiliary counterweight, measure the stacked block of metal. Measure the height, width and depth in inches of the auxiliary counterweight stack. H x W x D x .2833 will calculate the weight of the auxiliary counterweight in pounds. This number in pounds added to the built-in weight of the weightbox is the counter balance weight. See Section 4.0 Unit Specifications for built-in weight..
AMMETER
A clip-on ammeter may be used to compare the up stroke and down stroke current on electrically powered units. Balance the counterweight so that the current peaks are equal within plus or minus 5%.
