Controls
The “Power” switch on the SPS-IM controls both the operation and
the charging of the system. The unit will only charge from external
power in the power OFF position. In the power ON position, the unit
will operate directly from external power any time that it is being
supplied. Otherwise, it functions on internal battery power.
The “Output Selection” switch determines the polarity of the leading
edge of the TTL compatible output signal. In the “NON-INVERTING”
position, the output signal on the BNC connector will be a negative
going 5 to 0 Vdc TTL pulse derived directly from the conditioned sensor
output. When the “INVERTING” position is switch selected, the BNC
output signal will be a positive going 0 to 5 Vdc, TTL compatible pulse.
Recharging the Batteries
To recharge the SPS-IM Interface Module batteries:
1. Connect the recharger/power supply or external power cable
to the recharger input jack labeled “External DC”.
2. Connect the recharger/power supply into a working ac outlet,
or the external power cable to a dc power source of 5 to
15 Vdc.
3. Be sure the “Power” switch is in the OFF (CHARGE) position.
The red “CHARGE” LED will indicate that the batteries are
being charged. Allow 16 hours to fully charge.
4. Remove the charging source or move the “Power” switch to
the ON position once the 16 hour charge cycle is completed.
NOTE: When not in operation, do not leave the SPS-IM
continuously connected to a recharger/power supply or
5 to 15 Vdc external power for more than 16 hours as
this may damage the batteries.

SPS-5 SERIES - SPS With Remote Optical Sensor
The SPS-5 consists of the SPS-IM Interface Module described on pages 6
and 7, an ROS-5P Remote Optical Sensor with eight foot cable and
mounting bracket, and a R-5 (115 Vac), R-6 (230 Vac) or CA-SPS12 (5 to
15 Vdc) external power connection. One foot of T-5 Reflective Tape is
also supplied.
ROS-5P
When connected to the SPS-IM as described above, the ROS-5P
illuminates the target with a visible red light from a high intensity LED
and detects the reflected pulses from the rotating reflective tape target
with an internal photo-detector. The ROS-5P Remote Optical Sensor
is capable of detecting a reflected pulse from T-5 Reflective Tape targets
at distances of up to 3 feet [1 meter] and angles up to 45 degrees from
the target. The sensor is supplied with a set of two M16 jam nuts and a
90° angle slotted aluminum mounting bracket.
For most applications, a 1/2" [13 mm] square piece of T-5 Reflective
Tape should be applied to a clean area on the rotating object. The
sensor should be mounted and optically aligned to illuminate the
reflective target once per revolution. It is recommended that the
optical sensor be placed at a slight angle (approximately 10-15
degrees) from perpendicular, so that the sensor will detect only the
reflected pulses from the target. The sensor should be at least 2 inches
[50 mm] and no more than 3 feet [1 meter] from the target. The green
LED On-Target Indicator on the ROS-5P will blink at the input
frequency or be continuously illuminated when properly aimed.
Operating the SPS-5 as a triggering source
Once the ROS-5P input sensor is properly mounted and aligned, further
connections and operation should proceed in accordance with the
functions and descriptions under the SPS Interface Module sections
entitled ‘Connections’ and ‘Controls’ on pages 6 and 7 respectively.
