Overview

The LCD Display only functions as a display of the functions that are being used and also displays various Hourmeter measurements with the use of the Display (Momentary) Switch. This switch will allow you to toggle the LCD Display back and forth between the LCD displays. In case of Trio fault, the LCD will display the Trio Fault code on the LCD (diagnostic display).The following functions on the Scrubber are controlled directly by the PGDT Trio controller.

Traction Drive

Electromechanical Parking Brake (Optional)

Brush Head Actuator

Brush Head Motors

Solution Water Control

Squeegee Actuator

Solution Vacuum Motor

The following functions are controlled independently or in conjunction with the PGDT Trio controller. Recovery Tank Full Shutdown Electromechanical Parking Brake (Optional)

Recycle Pump Option Off Aisle Pump Option

The following Operator Inputs / Switches are wired directly to the PGDT Trio Controller. Vacuum/Squeegee Switch

Brush Head Up/Down Switch

Water Flow (Solution Increase / Decrease) Switch Soap Switch Option

One Touch (Default Controller Program) Switch

Forward / Reverse Traverse Control with Forward and Reverse Switches Traverse Speed PotentiometerSystem Power Up/Down:Critical Components:Key switch

Inhibit Relay

Key Circuit Breaker (5 Amp)PGDT Trio Controller

PGDT LCD Display

Control Operation:

Operator turns Key Switch to ON.The main (B+/36V) and (B-/0V) are always connected to the Trio Controller. The (B-/0V) is always connected to all other modules and controllers at all times. The Inhibit Relay turns ON. Upon the contacts closing on the Inhibit Relay, (B+/36V) is provided to (P-3 / Pin-18) on the Trio Controller. This provides input power to the Trio Controller and the LCD Display.There is an Internal Programmable Power down timer that will shut off the TRIO if the Key switch is on with no activity. This is factory set at 20 minutes.Note: This shut down function should not be used as an alternative to the key switch for proper powering down the machine. Only functions controlled by the Trio are shut down by the shutdown timer.

Brush Motor(s) Scrub Deck:Critical Components:

Brush Head ActuatorBrush Head Actuator Linear Potentiometer

Brush Motor(s)Brush Mode Switch (rocker switch)PGDT LCD Display

PGDT Trio Controller

Brush Motor Circuit Breakers (35Amps each) / (2each)Control Operation:

There are (2) two ways to lower the brush head scrub deck to the floor.

The first way is to use the brush momentary switch and toggle the switch in the + mode. By depressing the switch the brush head scrub deck will lower to the 1st scrub pressure setting. You can then increase the scrub pressure by toggling the brush momentary switch in the + mode.The second way is to use the one touch button on the Control Panel. This button is green color. By depressing the switch the brush head scrub deck will lower to the programmed scrub pressure setting. You can then increase the scrub pressure by toggling the brush momentary switch in the + mode. Each time you toggle the brush momentary switch the brush pressure will increase one level of brush pressure, to a total of (5) five brush pressure settings. If you continue to toggle the brush momentary switch to increase past the 5th programmed brush pressure setting, the brush pressure setting will not change. If in one touch mode, the pressure is too great for the setting selected, the Brush deck will automatically notify the operator. If the operator does not raise the brush deck- the machine will automatically raise the deck to maintain maximum pressure.With the linear potentiometer on the brush head actuator, the brush pressure setting will maintain a constant brush pressure on the floor. The voltage input from the linear potentiometer to the Trio controller will allow the brush head actuator to maintain a constant brush pressure over the surface of the floor.The brush motor(s) will operate when the scrubber is put into motion with the Forward and Reverse Traverse Switches to traverse in Forward or Reverse. The brush motor(s) will stop when the Forward and Reverse switches are released and the traverse is returned to neutral after approximately 1 second.To reset the HOME brush deck position:

Insure the brush deck is in the up most position. Hold the brush UP switch until you see a Code 0002 on the LCD Module. This is approximately 30 seconds. This will reset the HOME and maintain the same five brush pressure settings.Solution Water Flow

Critical Components:

Solution water flow control valve

PGDT LCD Display


Water Flow SwitchControl Operation:Solution water flow is enabled by the Trio when the scrub deck motors are running (see brush motor(s) scrub deck). The solution water flow stop valve is powered by P&G Trio controller (P-2 / Pins 8 & 9). The valve is energized (Open) while the brush motor(s) are running & de energized (closed) while the brush motor(s) are OFF.The solution water flow control valve is controlled by a pulse width modulated output from the Trio controller. The solution water flow control output is only enabled while the scrub decks are running and the flow is determined by the setting of the solution water flow bar graph on the PGDT LCD display. The rate of solution flow is adjusted by the water flow switch, by depressing the switch either in the (+) or (-) direction. The solution rate selected is displayed on the PGDT LCD Display as a Bar Graph.Vacuum Motor / Squeegee Actuator:Critical Components:

Vacuum Motor

Squeegee Actuator

Recovery Full Float Switch

PGDT LCD Display


Control Operation:

There are (2) two ways to turn ON the vacuum motor and lower the squeegee to the floor.

The first way is to use the Vac / Sq. Switch and toggle the switch in the Down position. By toggling the switch the vacuum motor will turn on and the squeegee will lower to the floor via the squeegee actuator. Depressing the switch in the Up position turns the vacuum motor off and the squeegee will raise up (after a programmed delay)The second way is to use the one touch button (green color) on the Control Panel. By depressing the switch the brush head scrub deck and squeegee will be lowered to the floor and the vacuum motor will turn ON. NOTE: The Vac/Sq. Switch must be placed in the center position for the squeegee function to operate correctly with the one touch feature.With either means of starting the vacuum / squeegee, you can depress the one touch button again when you have completed your job and the brush head scrub deck and squeegee will raise and the vacuum will turn OFF after a programmed delay.If you used the Vac /Sq. Switch to turn ON the vacuum and lower the squeegee, you can use the Vac / Sq. Switch and toggle it to the Up position to raise the squeegee and turn OFF the vacuum with the same programmed delay as in the One Touch Mode.When the Recovery tank float switch is tripped the P&G Trio controller is given an Inhibit signal of 0V on (P-3 / Pin-14). The LCD display switches to the diagnostic screen and the vacuum motor icon starts to flash. At the same time the vacuum motor is shut Off after a programmed delay.Traverse Transaxle Drive:Critical Components:

Traverse Transaxle Drive Electromechanical Parking Brake (Optional)

Traverse Potentiometer Forward and Reverse Switches

PGDT LCD Display


Control Operation:

The Potentiometer and Forward and Reverse Switches control the Forward / Reverse direction and speed of the Transaxle Motor and Drive. The Forward Switches are wired in series with the Wiper of the Potentiometer. The input of the Potentiometer and Forward Switches goes into the input of (P-3 / Pin-10) of the Trio Controller. The voltage at this input is 0V to 5V, with 0V as Neutral. When both of the Forward Switches are not activated or depressed by the Operator the scrubber will not traverse and the brush(s) will not run.

Electromechanical Parking Brake (Optional)

The Parking Brake can be used in one of two ways.

(1.) The Parking Brake is only applied when the Key Switch is turned OFF. When the Key Switch is turned ON the Electromechanical Parking Brake is released.

Note: The scrubber will not power ON with the Key Switch ON, if the Override Lever is engaged on the side of the Electromechanical Parking Brake.

(2.) The Parking brake is power with 36V from the Trio controller approximately 2 seconds after the scrubber is returned to Neutral.Fault codes on Trio LCD DisplayThe following are Fault Codes from the Trio Controller that may appear on the LCD display in case of a fault.
