D) Remote Shutdown
Remote shutdown of the PM via TTL signal is an option that can be wired
in at the time of installation.
A continuous 5V DC signal is required for engagement of the PM
shutdown circuit. To install the remote shutdown wiring, proceed as
follows:
1) Remove three screws on the top rear of the PM and lift off the cover.
2) Feed the (+) and (-) TTL signal wires through the wiring access port on
the rear of the unit.
3) On the main printed circuit board, locate terminals J3 and J6 near the
front of the unit. (Further identified as “SHUTDOWN” on 560 watt
models only.)

4) Solder or use .110” quick-connect terminals to attach the signal wires.
J3 to the (+) positive lead
J6 to the (-) negative lead
5) Replace the PM cover.
E) Local/Remote Alarm
A loss-of-output relay (form “C”) is wired to the output connector on the
rear panel. When wired to an external alarm or remote indicator lamp it will
alert the operator in the event of any condition which causes a loss of DC
output.
A color-coded wire “pigtail” with keyed plug is provided for wiring
convenience and to assure proper connections. The plug holds three wires
for the output fail relay.
The alarm may be wired with the relay “normally open” or “normally
closed”, as needed. The position of the contacts during DC output failure
and normal operating condition is illustrated below:

Note:
The three right-hand connector positions are unused in this installation
Relay contact rating for all models is 5a @ 30V DC
V) Options (Available from the Factory)
A) Charger Function Board
(Installed on Model PM-12-45)
The PM can be factory modified with the installation of a charger function
board. If the PM has already been installed and you wish to verify whether
this modification has been performed, check the left front panel of the unit.
If it has been so modified, there will be a label beside the output voltage
test points which reads “Charger Function Board Installed”. If the unit has
not been modified the output voltage adjustment pot will be exposed.
Installation of the charger function board will result in the operation of the
PM as a three stage “smart” battery charger. Once installed, this function is
automatic whenever the PM is in service.
Note:
Installation of the charger
board is not required for the unit to function as a battery charger. This
modification is necessary only if three stage charging is required, or if one
or more of the other special functions described below are required.
With the charger function board installed, each of the following installa tion/
performance options are available:
1) Three stage “smart” charging: Bulk, Absorption, Float
2) Selection of ideal charge regimen for either gel-cell or flooded lead-
acid batteries
3) Installation of an optional temperature compensation sensor for
optimal charging in high/low temperature environments
4) Installation of an equalize timer for periodic equalization of battery
plates (for use with flooded-type batteries only)
Note: Because the charger function board controls output voltage of the
PM automatically, the output voltage adjustment pot on the front panel is
disabled when this option is installed.
Following is a brief outline of each of these options. Complete explanation
of each special function is provided in the manual which accompanies the
charger function board.
