scan); the photosensor is dark.

Light On - The output (load) is energized when the light

is not blocked (retro and thru scan), or object is present

(diffuse scan); the photosensor is illuminated.

Two LED indicators are located on top of the sensor head.

Suffi cient light level turns the green light ON. When the

light level decreases to 150% of the minimum operating

level, the red light turns ON.

Plug-in timer/logic cards easily convert any ON/OFF MP Series photoelectric into a multifunction control. Seven

DIP switches located on the timer card provide the user with a choice of seven delay functions including dual

delay and motion detection. In addition, light operated or dark operated sensing can be selected by a switch

located on the photoelectric sensor head.

The timer/logic cards can be set up to modify the sensor’s head output signal. For instance, in thru-scan or

refl ective scan (L.O. mode), if the logic card is set for OFF delay the sensor does not immediately turn off its

output circuit after the beam goes dark or is blocked. Instead it waits until the beam has been dark for a preset

time. If set for ON delay, the sensor waits for a preset to time to recognize that the beam is complete.

Each timer/logic card has seven DIP switches to select ON delay, OFF delay, or both. The delays range as

Prior to inserting a multifunction timer card into the photoelectric sensor head, you must properly set DIP

switches located on the card. You must also set the L.O./D.O. switch located in the photoelectric sensor head.

On the top of the MP Series photoelectric sensor head is an access cover. When opened with a small blade

screwdriver, the multi-turn timer adjustment screws, labeled “1” and “2,” are exposed.

Clockwise rotation increases the time range(s). If a single delay option is selected, the other timer adjustment is

automatically set to zero. When the sensor head has been set to the desired timing range(s), snap the access

cover shut to provide proper head sealing.
