1-8 Installation
1-8-1 Installation procedure
(1) Mount the mounting stay to the installation area with wood screws or small screws.
Mount the main body onto the mounting stay with ornamental screws loosely tightened.
* In the case the mounting stay is attached to the main body, remove the two ornamental
screws from both sides and detach the mounting fittings.
(2) To the Actual count (UP terminal) on the input terminal block, connect the non-voltage
contact for counting up the input signals from relays, micro switches, limit switches, etc.
Also, establish a connection to each of the other input terminals as needed.
(3) Determine the angle at which the display panel (data display and LED
’s) is easy to see
and operate, and then fix the main body by fully tightening the ornamental screws on
both sides.
(4) Insert an applicable plug firmly into the DC jack and supply the power of DC12V/0.8A or
more.
(Applicable plug: φ2.1(I.D.) x φ5.5(O.D.) mm with center negative)
The main body has a build-in microprocessor, which means there is a possibility that the data
may collapse due to power fluctuation or flicker. Take power supply from a location free from
power fluctuation or flicker.
For the non-voltage contacts to be connected to the input terminal block, use the ones with less
chattering that can steadily turn on/off the voltage/current of 12V/10mA.
1-8-2 Input terminal block
For the input signals to be connected to the terminal block, use the ones with less chattering
that can steadily turn on/off the voltage/current of 12V/10mA. Keep a time interval of at
least 50msec between input signals. Also, keep 50msec or more from when one input
signal is turned off till another input signal is turned on.
