Installation
Carefully remove the PS1010T unit from its packing. Check that the unit is complete
and undamaged. The transmitter power input and output wiring are inserted at one side
of the unit, while the load cell input wirings are inserted at the other side. Therefore to
prevent noise coupling problems, it is recommended to separate the power and
transmitter output wirings from the load cell signal wirings. Terminals are standard
screw clamp type and accept wide range of wire sizes (14 AWG, max. for big terminals
and 18 AWG, max. for small terminals). There should be provision to ground the cable
shields to local (Mecca) ground, e.g. ground terminal on the DIN rail.
The installation location should be free of vibration. The transmitter should not be
located next to strong electrical fields and should have easy access to the module.
The supply voltage should be protected from a short circuit, via fuse or resettable fuse.
For application, which uses a four-wire load cell cable, two jumpers must be installed
bSEN to +EXC and between -SEN to –EXC. Figure 1 illustrates the electrical
wiring for the PS1010T transmitter module.
