Before you begin.
Read through and thoroughly understand the instructions before starting. The Microtec MkII Light
Control Module overview available on our website provides more detailed information that may
assist you when connecting and configuring your module. Specific instructions for connecting
your warning light to the module outputs are also available on the Microtec web site to make the
task quick and easy.
If your module is a latching (Thiess specification) unit it should be connected exactly the same as
a standard unit. Ensure easy access to the front panel during crane use and beware of the time
delays and latching function when performing final tests.
These Instructions.
The following instructions detail the input connections only to the Microtec MkII light control
module for a specific crane / computer type. For details of input connections for a different crane /
computer see the specific instructions for that machine or use the “overview” for customised
installations.
Reasonable care is exercised in the preparation of these instructions, but variations in machine
build may impact the accuracy from time to time and are beyond our control. These instructions
should be used by suitably competent personnel for guidance only.
Microtec products are warranted against defects in materials and workmanship for a period of 12
months from the date of purchase. Microtec will at its discretion repair or replace defective goods
within the warranty period. The warranty excludes failures caused by incorrect connection or poor
workmanship on the part of the installer. The users exclusive remedy and the suppliers sole
liability is limited to refund of the purchase price or replacement of any product shown to be
otherwise than as warranted. The supplier will not be liable for incidental or consequential
damages of any kind.
These instructions should be read in conjunction with the Microtec MkII Light Control Module
overview for detailed description of connections, specifications, and configuration.

Preliminary.
Set up the crane and check that the crane systems are fully functional and overload cut out
devices function as prescribed by the manufacturer. Check the satisfactory operation of override
switches and indicators.
External Warning Light / Output Connections.
Begin by installing a suitable warning light and buzzer to the crane exterior. Microtec
manufactures several versions designed for reliability & ease of use with the light control module,
see our website for details. Run the connecting cable inside to the Light Control Module. There
are many external warning lights available and the Light Control Module is fully compatible in the
vast majority of cases. Simple connection details for the most commonly used light fittings are
available at www.microteceng.com.au
Input Connections.
The Light Control Module requires electrical inputs from the machine to activate the outputs.
Some signals that may be required are:

•90% load or Pre Warning •All potentially unsafe overrides
•100% load or Motion Cut •Anti two block / overhoist alarm
Possible connection points from which these signals may be derived are detailed in table 1. Begin
by verifying the change in voltage for the given function at the prescribed connection points with a
volt meter. When sure of the connections isolate or disconnect the batteries before commencing
electrical work.
