Installation and adjustment instructions
vent-captor 3205.13/.12 S310/45
Please read carefully: No liability can be accepted for damage caused by improper use of the captor.
1.0 Installation:
With fitting G ½“ A (to be ordered separately), unit see drawing no. K722559
1.1 Installation depth
Dependent on duct or pipe diameter, min. 15 mm.
1.2 Flow direction
See under „Positioning“ in „Technical Information“
2.0 Electrical connection:
See „Connection diagram“ in „Technical Information“
3.0 Switching characteristics
3.1 Starting override time
The thermal time delay applies to a cold unit.
3.2 Switching delay
The time delay of the vent-captor is defined by the rate of change of flow speed relative to the set-point.
This time delay is not constant, the faster the change, the shorter the time delay. Depending upon
adjustment it varies from approx. 1 sec. to more than 5 sec. (3205.13/.12 S310/45).

4.0 Set-point adjustment
The vent-captor is factory set to a switching point of approx. 0.3 m/s and can be used without any further
adjustment.
4.1 Changing set-point:
Stable operating conditon reached 5 minutes after electrical connection.
4.11 Decrease sensitivity = higher set-point, turn potentiometer clockwise
4.12 Increase sensitivity = lower set-point, turn potentiometer counter clockwise
The following instructions refer to output PNP n. c. (.12)
4.2 With no air flow turn adjustment potentiometer counter clockwise until LED „ red“
This position sets switch-point to zero flow. Slowly turn adjustment potentiometer clockwise until LED
„green“ = most sensitive setting. Further adjustment, max. 18 turns results in least sensitivity.
Attention: 18 turn potentiometer without mechanical end point.
5.0 Monitoring air flow failure (air flow below set-point)
5.1 After 5 minutes with no air flow, turn potentiometer counter clockwise until LED „red“
5.2 Turn on normal air flow, wait 3 minutes, turn potentiometer clockwise (counting the turns) until LED „green“
5.3 Turn back half the number of turns at 5.2 = optimum setting, tr  tf (s. page 1/3 )
6.0 Monitoring lower flow limit
6.1 Reduce flow to the min. rate at which a signal is required.
6.2 After 5 minutes slowly turn pot. clockwise until LED „green“
6.3 Increase flow to normal rate, wait 3 minutes, if LED „red“, setting is correct.
6.4 If LED stays „green“ the flow rate difference is too small. In this case turn potentiometer slowly counter
clockwise until LED „red“.
7.0 Monitoring upper flow limit
7.1 Increase flow to rate at which a signal is required.
7.2 Turn pot. clockwise until LED „green“
7.3 Wait 5 minutes turn pot. slowly counter clockwise until LED „red“
7.4 Decrease flow to normal rate. Wait 3 minutes, if LED „green“ setting is correct.
7.5 If LED stays „red“ the flow rate difference is too small. In this case turn pot. clockwise until LED „green“.
