Operating Procedures
6.1
Converter Modules
Refer to UM1C24481500 (Converter Module User Instructions) for converter module operation instructions.
6.2
Using the Converter System with an ACU+ Controller
The following outlines the steps to set-up the converter system to be used with an ACU+ controller. Refer to the ACU+ Controller
User Instructions (UM1M820BNA) for ACU+ operation.
•
Set switch position 4 of S1 to the “ON” position. See Figure 3.1.
•
Remove (and store) Jumper P2. See Figure 3.1.
•
Connect terminal 1 (CANL) and 2 (CANH) of TB2 to the CAN bus the ACU+ resides on. See Figure 4.2.
NOTE!
The converter system must be the last device on the CAN bus to function properly.
NOTE!
If the converter system is used with control/monitoring via an ACU+ controller and the converter input is powered
through a distribution device in the host system, the ACU+ controller should not be set up to calculate battery current. If
battery current measurement via the ACU+ is desired, the host system must measure battery current with a battery shunt.
6.3
Local Indicators and Test Points
Refer to the Converter Module User Instructions (UM1C24481500) for descriptions of the local indicators located on the converter
modules.
Refer to this section for descriptions of the local indicators and test points located on the main shelf’s front door.
6.3.1
Local Indicators
The following local indicators are provided on the front door of the main shelf. Refer to Figure 6.1.
a)
Circuit Breaker or Fuse Open (Red LED):
Illuminates red if any distribution fuse or circuit breaker in the system opens.
b)
Input Voltage OK (Green LED):
Illuminates green when input voltage is above 22.5Vdc ±0.5Vdc. This indicator is off if the
input voltage to the system falls to 20.5Vdc ±0.5Vdc.
c)
Converter Critical (Red LED):
Illuminates red if more than one converter module fails (or if only one converter module is
installed in the system and it fails). Alarm conditions are as stated in d) below.
d)
Converter Major (Yellow LED):
Illuminates yellow if one converter module fails. Alarm conditions are as follows.
•
A converter module reports a high voltage shutdown condition (HVSD).
•
A converter module reports a fan failure.
•
A converter module reports an EEPROM failure.
•
A converter module reports a converter failure.
•
A converter module reports a low input voltage condition.
•
A converter module reports a high temperature condition.
•
A converter module reports a thermal derating condition.
