Dol Sensors Hedelund 4, Glyngøre
Capacitive sensor for grain, feed, granulates and liquids.
DOL 33R has a built in change over contact and adjustable time
delay.
Mode of operation: DOL 33R has delayed switch off. The relay
switches as soon as the sensor is activated, but when the
activation ceases, there is a delay before the relay switches back.
See Figure 1. The red control lamp indicates state of function of
the sensor and the relay. Please note that quick flashes = small
time delay and slow flashes = big time delay. See Figure 2.
Mechanical mounting: Mount the DOL 33R so that at least 10
mm of the sensor end is free. Can be mounted effectively in a PG
36 gland.
Electrical mounting: The supply voltage is connected to the
brown and the blue wire. DOL 33R is available in 230 V ac. The
actual voltage appears from the label on the sensor. Connect the
load (motor, motor relay etc.) in series with the relay switch of
the sensor. Fuse max. 6.3A. See Figure 3.
Adjustment: The time delay can be adjusted by the small
screwdriver in the open hole. Clockwise to increase the delay.
The sensitivity can be adjusted in the other hole (first remove
sealing). Clockwise to increase sensitivity. See Figure 4.
Checking the switch: When there is no supply voltage to the
sensor, 1 and 4 are closed, and 1 and 3 are open. See Figure 1.
SKOV A/S also produces a sensor with the opposite time
function, delayed switch on. This type is called DOL 45R.
