Power Up and Initial Checkout
Ensure power wiring to the controller is ready—see the the “Power Wiring” section
on page 15. See Figure 3 on page 11 for the location of status LEDs and connectors.
See Figure 4 on page 16 for the location of the NPB-PWR module’s power connector.
After completing all mounting and wiring, do the following:
Procedure 7 Initial power up and checkout.
1 Apply Power.
2 Check the Status LED.
Also see the section “About Backup Configurations” on page 23.
Apply Power
To apply power, insert the power plug into either the NPB-PWR module, or if using a
WPM-
XXX
wall adapter, the controller. If using the line-voltage input NPB-PWR-UN
power supply module, energize the 120–240Vac circuit wired to the module.
Caution Do not connect both the WPM-XXX and NPB-PWR / NPB-PWR-UN
supplies at the same time, or equipment damage may result.
Check the Status LED
When power is applied, the green LED labeled “STATUS” will light. This indicates
that the system is OK, with power applied. When the controller finishes booting, the
yellow “BEAT” LED should be blinking steady at a 50% duty cycle, typically at a 1Hz
rate. In most cases, this blink pattern starts about 30 seconds after power is applied.
If after applying power, the STATUS LED goes out, or if the BEAT LED comes on
(steady) and stays lit over 2 minutes, contact Systems Engineering for technical
assistance. See the “Status LEDs” section on page 25, especially “Heartbeat”.
About Backup Configurations
A JACE-3E (T-300E) or JACE-6E series (T-600E) controller allows two separate and
configurable methods to preserve unsaved station data when "power quality events"
occur, including loss of primary power or low-voltage dips (brownout):
• Using the integral static RAM (SRAM) on the controller’s NPM3E or NPM6E
processor module. This default method can allow the unit to operate “bat-
tery-less”, that is, without installing the optional NiMH battery pack. Note in this
configuration a controller reboot is likely to occur whenever a power outage or
voltage dip is sustained for more than one AC line cycle (1/50th or 1/60th of a
second) or a number of line cycles, depending on the load and power supply. Crit-
ical station data will already be saved prior to any power quality event, but the
NiMH battery option is available to prevent nuisance controller reboots/station
restarts during extended or frequent power outages.
•An optional on-board NiMH battery pack. Installing this battery allows the con-
troller to continue operation (without rebooting) over short power outages or
brownouts lasting several seconds (or if also using SRAM, up to 10 minutes). For
