Remote Radio Power
When the VERSA-TECH
®
Recloser is in service with a load current of 10 Amps or more, the attached remote radio is on and powered from
the recloser's internal current transformers. If the recloser is not in service or the load current is less than 10 Amps, the radio is ON only for
10 minutes and must be powered from the recloser internal batteries. To turn on the radio, pull down the Non-Reclosing handle (red lever)
and then push it up. The radio then will automatically shut off after 10 minutes of communications inactivity to minimize battery drain. If the
Non-Reclosing Lever is left in the down position without the ample 10 Amps of load current, wireless communications will time out in 60
minutes.
NOTE: Whenever the remote radio on the recloser is changed or swapped with another remote radio, make sure that the battery is pulled
out of the recloser for at least 60s for the control to completely reset. After the reset, plug in the new remote radio to the DB 9 port of the
recloser followed by the battery pack insertion. This process lets the remote radio get correctly identified by the Versa-Tech Programmer.
Radio Operation
The Digi/XBee and SiFLEX radios communicate with each other on a 900MHz channel which utilizes frequency hopping to minimize
interference from other radio frequency sources. The RF modules are FCC compliant. The communication range is up to 500 feet open air.
The radios use a two-part addressing scheme to help ensure that messages from only authorized sources are passed to a recloser.
First, all VERSA-TECH
®
Recloser local and remote radios have a unique user transparent address which is transmitted during
communications. The recloser local radio will accept messages only from a remote radio with the same address. This helps prevent other
900MHz radios from making unauthorized communications with VERSA-TECH
®
Reclosers.
Second, each remote radio is programmed with a unique fixed radio communications address. This address allows users to differentiate
between multiple reclosers all within a 500-foot transmit/receive range. The remote radio will discard any message that does not include
its unique radio communications address. The local radio has provisions through the recloser programmer software (see Section 6) which
permits selecting any recloser's remote radio communications address.
