6. CERTIFICATIONS AND COMPLIANCES:

SAFETY

IEC 1010-1, EN 61010-1: Safety requirements for electrical equipment for

measurement, control, and laboratory use, Part 1.

ELECTROMAGNETIC COMPATIBILITY

Note:
1. Self-recoverable loss of performance during EMI disturbance at 10 Vrms:

For operation without loss of performance:

Install 1 ferrite core RLC #FCOR0000 or equivalent, to power cable at unit.

I/O cables are routed in metal conduit connected to earth ground.

7. FIELD CONNECTIONS: Removable screw terminal blocks.

8. WEIGHT: 1.25 lb (0.58 kg)

STATUS LED’s

Three LED’s provide status indication and are described in Table 1. The

PROFIBUS–DP state machine is indicated by the data, WD and DP LED’s and
are described in Table 2.

WIRING AND CONNECTIONS

POWER SUPPLY REQUIREMENTS

The Operator Interface requires an 11 to 30 VDC power supply rated at

2.25 W unless otherwise stated on the label.

!

The terminal may take as little as 100 mA in certain circumstances, so be

sure that the chosen power supply can operate correctly with this load.
Large switch-mode supplies tend to need a certain minimum load before
they will operate correctly.

In any case, it is very important that the power supply is mounted correctly if

the unit is to operate reliably. A very high proportion of reported problems are
caused by incorrect power supply installation, so please take care to observe the
following points...

!

The power supply must be mounted close to the unit, with usually not

more than 6 feet of cable between the supply and the PAPBH. Ideally, as
short a length as is possible should be used.

!

The wire used to connect the PAPBH’s power supply should be of at least

22 gauge wire. If a longer cable run is used, you should use a heavier
gauge wire. The routing of the cable should be kept away from large
contactors, inverters and other devices which may generate significant
electrical noise.

RS232 PORT PIN OUT

Both HMI and PC ports are RS-232 ports and have the same pin-out

described below. The following illustration and table gives the pin-out of these
ports to enable such connections to be made.

The above table denotes the pin names of the RS-232 port. When connecting,

the pin name at the port is connected to the opposite of that pin name at the
destination device.

PROFIBUS CONNECTION

It is recommended that PROFIBUS plug connector such as Siemens part

6ES7 972 – 0BA00 – 0XA0 be used. If the PAPBH is the last unit on the
network, set the terminating resistor switch to the “ON” position.
