Start:
This switch “arms” the emergency stop circuit. If the emergency stop button is used to stop
the machine (whether in an emergency or not) it will be necessary to depress this switch be-
fore the machine will run again. Whenever the power to the machine is disconnected and re-
connected, it will be necessary to depress this switch before the machine will run.
Speed/Distance indicator:
This device will measure and display the distance traveled by the cable and also the speed at
which the cable is traveling. The functions are controlled by the small push button on the right
of the display. If this button is depressed, the display will “toggle” between speed and dis-
tance. If held down for more than three seconds, the display will reset to zero. Before starting
an installation, it will be necessary to depress the button for more than three seconds to set
the distance display to zero. Should it be necessary to replace the speed distance measuring
indicator, it will be necessary to reprogram it. See appendix 3
To install cable:
For the first time installing a cable type that has not been installed before and whose charac-
teristics are unknown.
1. Connect the power to the machine. The power supply should be nominally 115 volts single
phase AC 50 or 60 Hz. This may be derived from an IC engine driven generator, domestic
or industrial electrical supply. The power source should be fitted with a suitable connector,
see “Connect the electrical supply to the machine”. Page 15 of this manual.
2. Turn the torque control knob left, to the maximum counter clockwise position.
3. Turn the speed control knob to a position midway (11:00) between the maximum counter
clockwise and maximum clockwise position.
4. Press “start” button.
The machine will try to push the cable, with the torque control set to a minimum the rollers will
not turn or only very slowly.
It is now necessary to set the torque control to a position appropriate to the stiffness of the
cable and the characteristics of the cable insulation. See appendix 2 for recommendations. If
the cable type has been installed before, the settings will be available, the torque control knob
may be set at the previously determined position.
Set the torque control knob to the position determined above. The rollers will now start to turn,
and the cable will feed through the air box. When the cable has traveled a reasonable dis-
tance, (approximately 165 feet) turn on the air, this will help the machine to feed the cable.
The tube route through which the cable is to be fed, should be configured in such a way that
the cable can feed all the way along the tube and out the other end. It will be necessary to be
able to determine when the cable has emerged at the other end of the tube route. A typical
way of achieving this aim is to have a colleague positioned at the end of the tube run, in con-
tact with the main installer using a radio. In this way the main installer will be advised when
the cable has completed the run, so he can then stop the machine.
If there is an unexpected obstruction in the tube route, the rollers will see this as an increase
in torque demand, assuming the torque control has been set at an appropriate level. The roll-
ers will stop turning before they push the cable so hard as to cause it to buckle. If (due to lack
of previous knowledge of the cable characteristics) the torque control has been set at a figure
which is too small to push the cable, the setting may be increased. Bear in mind that this will
increase the risk of the cable being damaged by buckling.
