Operating Instructions PCA-2 1000D2 Product overview Any other use above and beyond this will be considered as improper use. The manufacturer will not be liable for any damage resulting from this. The company using it bears the sole risk. 3 Product overview 3.1 Function Sensor-control module with differential-pressure sensors in proven ceramic-cantilever technology for climate and clean-room application. The pressure range goes from 0...1000 Pa (0...4.0 in.wg), four measuring ranges are programmable.

Operating Instructions PCA-2 1000D2 Electrical installation 5 Electrical installation 5.1 EMC-compatible installation of control lines Pay attention to maintain sufﬁcient distance from powerlines and motor wires to prevent interferences. When using a shielded cable the shield must be connected (as short and with as low an induction as possible!) to the PE conductor on one side at the signal input (of the evaluation unit). 5.
PAGE 11
Operating Instructions PCA-2 1000D2 Electrical installation speed controllers are no longer controlled. This means that all fans stop! 5.4 Digital input (D1) Different functions can be assigned to the digital input D1(see IO SETUP). A voltage at terminals “1” and “2” (10...24 V DC) activates the programmed function (note polarity - see connection diagram). 5.5 Relay outputs “K1” The relay output “K1”can have different functions assigned to it, see IO SETUP. Max.

Operating Instructions PCA-2 1000D2 • • • Electrical installation dissimilar potential (over 10 V!) will lead to the destruction of the RS-485 interface (e.g. lightning). Except the data link “A (D+)”, “B (D-)” and “GND” (for automatic addressing additional “ID1” - “ID2” see following chapter) no further cable cores of the data line may be used. Pay attention to sufﬁcient distance from powerlines and motor wires (min. 20 cm).

Operating Instructions PCA-2 1000D2 Electrical installation Information • Except the data link “A (D+)”, “B (D-)” the “ID1 - ID2” and the “GND” connection may no further cable cores of the data line be used. • The connections for the automatic addressing “ID1” and “ID2” are not directly connected with each other internally. These may not be bridged; any order of connection is possible.
