4. General operating with Pendant:
a. DO NOT put excessive force on the pendant during
use. It is tested to 70 pounds of pull force, but it is not
a handle.
b. Always check out the machine function while still in a
safe location to insure proper function.
c.
Power the PQ 500 up by pressing the ON button.
This will result in the Red LED lighting for 10 seconds,
followed by the Red LED going out with the Green
LED lighting. You can now run the machine with the
UP and DN buttons as appropriate.
d. Ensure that the E-OFF function is operable by powering PQ 500 up, then pressing the E-OFF button. All LEDs
should go out within one second.
e. Restart the machine by pressing the OFF button followed by the ON button.
f.
The Pendant remote can now be used while suspended below the PQ 500.
5. Optional Bite Switch Function with a Pendant:
a. Ensure manual switch on the ascender is
in the “UP” position.
b. Connect pendant to ascender, making sure the
connector is tight.
c.
With the ascender turned “OFF”, plug in the bite switch to the back of the pendant (see Figure 17).
d. Ensure the selector switch is in the proper position, as this will determine the direction of travel.
e.
Press the “ON” button on the pendant.
f.
Use the bite switch to approximate the trigger on the pendant. Use approximately 10 lbs of force to activate the
bite switch.
6. When operated in this configuration a lanyard must be attached to the manual brake release lever. (The Manual Brake
Release Function is described in detail in section 8.8.)
This allows operation of the manual brake by simply reaching above your head and tugging on the lanyard.
To rig the configuration:
a. Attach a strong cord (4 mm prussic cord) or lanyard to the ring on the manual brake lever.
b. Route the cord through the carabineer at the base of the machine so that it hangs down approximately 1 foot,
within easy reach of the operator. In this way, pulling down on the cord will pull the brake lever towards the
base plate of the PQ 500 releasing the manual brake.
For more information on rigging see section
8.9.
Brake function
1. Automatic brake
—the automatic brake allows for either local or remote control. That is, the control is only to tell the
motor to go forward or reverse. No command results in stop.
2. The brake on the PQ-
500 is automatically applied as the motor function. That is, if the motor is commanded to “up” it
first releases the brake, then powers the unit up.
3. The brake is a multi-plate device with three rotors and four stators. The rotors are stainless steel while the stators are
oilite bronze.
4. A pressure plate is spring-loaded and presses on the stack of rotors and stators.
5. A throw out device is actuated by torque from the motor.
