5. DIL Switch Settings
There is one 8-position switch located on the top side (DIL1), and another 8-position switch is
located on the bottom side of the unit (DIL2). These switches provide major settings of the
desired properties of the unit.
Changes of switch settings will become active only after cycling the power
supply of the unit!
Positions 7 and 8 of switch DIL2 are for internal factory use only and must
both be set to OFF at any time during normal operation
5.1. Basic mode of operation and power-down memory setting
Positions 2 and 3 of switch DIL1 on the top side set the mode of operation, and position 4
allows setting of the power-down behavior of the unit:
1
2 3 4
5 6 7 8
on on
on off
off on
off off
Mode of operation
Input A only
Quadrature operation A / B / 90°
Sum A + B or difference A - B
A = counting input, B = direction control (up/dn)
DIL1
Position 4 off: Power-down memory off. Upon power up the counter either resets to zero or sets to the
value programmed under parameter „Set Value“ *)
Position 4 on: Power-down memory on. Upon power up the counter re-loads the previous value before
power down
