CONNECTIONS & CONFIGURATION SWITCH SET-UP FOR VARIOUS SENSOR OUTPUTS
Note: Separate power supplies must be used for sensor power and input power to maintain the isolation breakdown voltage specification. If isolation between power
and input is not needed, then a single supply can be used for both unit and sensor power.
The SW-100 Speed Switch uses a comparator amplifier connected as a
Schmidt trigger circuit to convert the input wave form into the pulse form
required for proper circuit operation. Three set-up switches are used to configure
the input circuit to accept signals from a wide variety of sources, as follows:
S1 - ON: Connects a 1 K
Ω pull-down resistor for sensors with sourcing outputs.
(Maximum sensor output current is 24 mA @ 24 VDC output.)
S2 - ON: For logic level signals, sets the input bias levels to V
IL
= 2.5 V,
V
IH
= 3.0 V.
OFF: For increased sensitivity when used with magnetic pickups, sets the
input bias levels to V
IL
= 0.25 V, V
IH
= 0.75 V.
S3 - ON: Connects a 3.9 K Ω pull-up resistor for sensors with current sinking
output. (Max. sensor current = 3 mA.)
INPUT CIRCUITS, SENSOR CONNECTIONS AND CONFIGURATION SWITCH SET-UP
CONFIGURING THE SW-100
Upon entry to a set-up parameter, the Input LED blinks the current numerical value of a setting at a 1 Hz rate. A setting
of “1” is indicated by one blink (½ sec on, ½ sec off), through a setting of “9”, which is indicated by nine blinks. A setting
of “0” is indicated by a single short flash (40 msec on, 1 sec off). After the entire value is indicated, the SW-100 pauses two
seconds and repeats the value.
During entry of a new value, if the Mode switch (S4) or any of the CFG DIP switch positions are changed before the push
button is pressed, the SW-100 aborts the entry process and retains the previous setting.
To begin set-up, place DIP switch 4 to the on (up) position. DIP switches 5, 6, and 7 access unit configuration settings.
Note: To return to normal operation,
place DIP switch 4 in the down
(RUN) position.

MAGNETIC PICKUPS
RECOMMENDED RULES FOR MAGNETIC PICKUP CONNECTIONS
1. Connect the shield to the common Terminal “9” at the input of the SW-. DO NOT
connect the shield at the pickup end. Leave the shield “open” at the pickup and insulate
the exposed shield to prevent electrical contact with the frame or case. (Shielded cable,
supplied on some magnetic pickups, has open shield on pickup end.)
