2.3.2. Back face (8) Power switch (SW1) This switch turns ON/OFF the FF/FM311DR. (9) Fuse (Contained in fuse holders FU2 and FU3) 0215004. MXP made by Littelfuse (5 × 20 mm 250 VAC 4 A time lag type complying with RoHS)
Installation Install the FF/FM311DR on a solid and horizontal floor (or table) so that screws can be fed from the top face, setup can be carried out from the front face, and the power switch can be operated from the back face, for correct vibration to be performed for screw alignment (see the figure shown below).
Preparation of operation Before starting operation, make preparations as follows: 4.1. Connection of screw feeding hose When connecting the screw feeding hose WARNING (1) Make sure that the air supply is shut down. (2) Fix both ends securely. If the screw feeding hose comes off with air being supplied, a screw fed by compressed air may jump off from an end of the hose, leading to injuries (if it hits your eye, you may lose your sight) or damage to equipment around the machine.

Connect the cables to the FF/FM311DR in the following procedure. (1) Confirm that the power switch of the FF/FM311DR is turned off. (2) Connect the cables securely to the specified positions as shown below. Be sure to tighten the fixing screws if installed in the plugs.
4.4. Loading screws Opening the screw inlet cover, load the screws conforming to FF/FM311DR specifications into the basket. Do not load the screws exceeding the height of the partition plate (red mark). Close the screw inlet cover after you have loaded the screws.
POWER LED (green) goes off before turning on the power switch. (2) Do not turn on/off the power many times in a short time. Otherwise, the useful time of the FF/FM311DR may be reduced and failure may happen.
In sync with the screw tightening operation, input a screw feeding signal from an external control device, such as a PLC, into the No. 7 pin of the FF/FM311DR external I/O receptacle (CN IO). With this signal, the FF/FM311DR starts to feed screws by compressed air.
(Each machine is shipped from the factory with the parameters set in accordance with specified specification.) 6. Explanation of operation This chapter explains the operation of the major parts of the FF/FM311DR. (Refer to “6.2 Operation time chart” described below.) 6.1.
6.1.3.2. For handheld driver type With the screw feeding signal from the switch in the handheld driver tool, the screw feeding solenoid valve and the track driving vibrator (to be more precise, Pa.41 + Pa.87 for the track driving vibrator) start operations for a preset time (Pa.41).
6.2. Operation time chart 6.2.1. Screw feeding The following figure shows the operations of major parts. Caution: You can select only one type of screw feeding signal according to the specification. Absence of Photoelectric sensor on screw(ON) the track for detecting a screw Presence of screw(OFF)
This adjusts the operation time of the solenoid valve for feeding the screws. Adjust the time so that a screw at the FF/FM311DR can reach the chuck unit of the driver unit. The screw feeding time is influenced by the screw size, air pressure, screw feeding air flow rate, and screw feeding hose diameter etc.
7.2. Adjustment of screw feeding air flow rate This adjusts the air flow rate at screw feeding operation. To adjust the flow rate, loosen the lock nut (as shown in the figure below) and rotate the speed controller according to the table below. The air flow rate is influenced by the screw size, air pressure, screw feeding time, and screw feeding hose diameter.
7.4. Adjustment of vibrator vibration frequency This adjusts the speed of the screws traveling along the track. The following figure shows an approximate relationship between the vibrator vibration frequency and the vibrator vibration strength. Although the vibrator vibration strength is largest near the resonance frequency as shown in the figure. However, we recommend that the frequency be adjusted to a frequency a little higher than the resonance frequency for stable vibration.
7.7. Adjustment of photoelectric sensor The photoelectric sensor is mounted on the top of the track. When the screws aligned on the track reach the detection position of the photoelectric sensor and the photoelectric sensor turns ON, the hopper track stops swaying and the vibrator stops vibrating automatically.
7.8. Adjustment of track and upper guide In order to transfer screws on the track toward the escapement unit smoothly, it is necessary to position the upper guide properly. A proper relation between the track and upper guide is shown in Fig. 35;...
Proper mounting position Improper mounting position Screws are not fed smoothly Screws are not fed because the There is a proper level difference because the position of the screw position of the screw receiving plate between the track and the screw receiving plate is too low as is too high as compared with the receiving plate.
Fully understand the functions before the setup and adjustment. Functions of FF/FM311DR are limited in the setup and adjustment mode. In such a status, screw feeding may not be carried out correctly.
8.1.2. Functions of setup keys Functions of setup keys on the setup panel are as shown in the table below. Functions Keys Designations • Setup item number can be selected (item number is increased by one) UP key • Setup value of selected item can be changed (setup value is increased by a step) •...
( ) When the machine starts normal running, components of FF/FM311DR start operation. Make sure that the normal running indication status is restored, and then, carry out setup and adjustment. Ensure that all the LEDs are lit up in the LED check 4 status. If any LED is faulty, correct indication during setup or adjustment work is disabled.
