2.2.1.1 A - Supply Connector

The Reader requires a single DC supply voltage (10 to 24 V) through a 2-pin connec-

tor marked with + for positive and – for negative

The Power Range Setting wired jumpers (marked J in Figure 3) and the actual power

supply have a direct consequence on the operating temperature of the reader as

shown in Table 2.

Pins 2 + 3 connected 18 - 24 V -20º to +70º C

CAUTION:

1. In order to operate the reader over the full temperature range

with pins 1 + 2 connected (15 to 24 V), the maximum current

consumption must not exceed 0.9 A

peak

. Exceeding this

value could result in unreliable functioning of the dynamic

auto tuning, or sharp limitation of the transmitter output

power because of internal protection. If either of these should

occur, switch the device off and allow it time to recover; and

then when it is switched on again it will revert to normal oper-

ation. Note that if either of these occur it is an indication that

the reader is not being operated within its specifications.

2. The reader itself generates heat, therefore if it is incorporated

into a housing you must ensure (by proper design and/or

cooling) that the temperature immediately surrounding the

reader does not exceed the operating temperature range.
