Installation of the ME401-2 in machinery
In this section possible installation proposals are given. The installation proposals are
listed as examples and can be used as a guide for inspiration for an actual installation.
Standard installation of ME401-2 for registering operating hours:
For a standard installation in machines where the unit should register the number of
operating hours use the connections as follows:
1 Red Power Connect to a fixed DC supply through
a fuse of 1 Amp.
2 White Digital input 1 Connect to the operating hours
counter.
(Min. 8V DC voltage at the input)
3 Brown Digital input 2 Connect to the ignition signal
(Min. 8V DC voltage at the input)
4 Grey Digital input 3 Can be connected to an external
sensor or it can be connected to a
ID06 Card reader.
(Min. 8V DC voltage at input)
5 Pink Digital input 4 Can be connected to an external
sensor for detecting a critical running
mode or an alarm
(Min. 8V DC voltage at input)
6 Green 1-wire input Can be used to connect one or two
temperature sensors or a Dallas Key
reader to control an immmobilizer
relay connected to Digital output 1
7 Yellow Digital output 1 Can be used to control external
equipment through a relay (see
example in “Installation of the digital
output”. Max. Load 200 mA)
8 Blue Ground
Installing the ME401-2 as to surpass the main switch on the machine:
In case the main switch on the machine will break the negative wire (Ground wire), the
inputs may register a voltage level and start counting operating hours. To avoid this
situation the digital input 4 (Pink wire) should be connected to the chassis/ground on the
machine. Then send the following SMS to the unit (phone number) to activate the filtering:
