Time Switch 4 Channel REG 372 5WG1 372-5AR01

Siemens AG REG 372, 4 pages Technical Manual

Product and Applications Description

The time switch REG 372 is a DIN-rail mounted device laterally attached to the bus coupling unit REG 110 (to be ordered separately, order number: 5WG1 110-5AR01). During this it occupies 4 addressing locations of the bus coupling unit. Via the four channels time controlled applications such as illumination, heating or shutters can be switched on or off. It can be used as daily, weekly or yearly clock controller. By connecting an aerial FA and a power unit NT DCF77 the clock controller itself automatically sets the up-todate daytime and date (MEZ).

With a reading button the set switching times, date referenced inputs and 1x-switching commands can be trialled.

The bus coupling unit REG 110, the power unit NT DCF77 and the radio aerial FA are not contained in the volume of delivery and must be ordered separately

Mounting and Wiring

General description The N-system DIN-rail device can be installed to Nsystem distribution boards, surface or flush mounted, or to any available DIN-rail EN 50022-35 x 7,5. During this the electric connection between the clock controller and the bus coupling unit is established via the lateral physical external interface (PEI). The bus coupling unit is not contained in the volume of delivery and must be ordered separately.

Mounting DIN-rail devices

(Figure 2)

- Slide the device (B1) onto the DIN-rail (B2) and

- swivel back the device until the slide clicks into place

audibly.

- Remove the protection film of the adhesive tape (B4),

slip the device to the right and connect it with the bus coupling unit (B3)

Figure 2: Mounting of the DIN-rail device

Dismounting DIN-rail devices

(Figure 3)

- Slip the bus coupling unit (C1) to the left until the

plug-in connection to the bus terminal unit (C2) is exposed,

- press down the slide (C4) with a screw-driver and,

click it into place by a slight pressure and

- swivel the device (C1) from the DIN-rail (C3).

Figure 3: Dismounting the DIN-rail device

Connecting terminal line aerial FA (Figure 4)

- Remove approx. 5mm of the insulation of the conduc-

tor (D1.1), plug it into the connection blocks (D1) and tighten the screws (D1.2)
