The weighing device SBT WD2005 by SIEMENS indicates the loss of a critical mass of extinguishant from the

cylinders.

The weighing device set consists of weighing device plus counterweight depending of the cylinder volume.

S54476-S45-A1 = S54476-B45-A1 + S54476-B52-A4 (counterweight 1.5 kg for 67 L)

S54476-S45-A2 = S54476-B45-A1 + S54476-B52-A5 (counterweight 2.0 kg for 80 L)

If the weighing device is to be used outdoors, it must be protected against the ingress of water.

mass loss indication adjustible 5% - 10%

Operating Principle

The weighing device operates on the principle of an eccentric pivot.

An adjustable position balance weight mounted on the weight spindle enables the device to be set to indicate

the mass loss over a range of gross loads. If the cylinder weight and the balancing weight are equal, the

system is stable (balance weight is in the horizontal ‘set’ position). If the net weight reduces (due to leakage

from the cylinder) the balance weight drops downwards (balance weight moves to the inclined ‘tripped’

position). The weighing device is adjusted to indicate a loss of mass of 5% from the suspended cylinder.

The weighing device must be reset manually to resume its function.

Procedure 1. Place the trapeze nut into the suspension rail, feed the trapeze spindle of the weighing device through the hole in the suspension rail and screw the slightly greased trapeze spindle into the trapeze nut until it appears at the end of the nut. 2. Secure the two trapeze nuts at the lower end of the spindle to each other (counter). 3. Bring the two thread rods (M10) into the weighing device and secure them flush in the 2 hut nuts. 4.

The weight spindle moves to the ‘tripped’ position (pos. 3). Trick: At start turning weight lift spindle manually to horizontal until selfhoding noticeable. 2. Holding the weight spindle in the ‘set’ position, rotate the Balance weight(s) on the weight spindle, until the weight spindle remains in the balanced position (pos. 2). 3.

Maintenance instructions Warning! Only readjust the balance weights each time the cylinder is removed from the weighing device for refill or when it cannot be guaranteed that a filled cylinder will be refitted to its original weighing device. Do not adjust the position of the balance weights during routine servicing or due to the weighing device having tripped.
