SMR parameters programmed by CSU
In the SMR menu on the CSU:
• Current Limit
• High Voltage Shut-Down (HVSD)
• High Voltage Alarm
• Low Voltage Alarm
• Latched Fault Reset
In the Battery menu on CSU:
• Float Voltage
• Equalise Voltage
Test Function: (when activated on CSU)
SMR front panel LEDs are switched on and off in
sequence Green – Yellow – Red.
Alarms and monitoring
Front Panel LED Indication Table:
Green Yellow Red Condition
Off Off Off No AC power
Blink Off Off Primary power bad
ON Off Off Normal
ON Flash Off Alarm
ON ON Off Equalise
Off Flash ON Shutdown
Flash Flash Flash Firmware upload
Note: in case of microcontroller failure status of the
LEDs is undefined.
Primary
power bad:
Indicates the input AC is too low or too
high, or the primary circuit is faulty;
Alarm:
See Alarm table;
Shutdown:
SMR is shut down by remote control, or
not fully plugged in, or there is an
internal control circuit fault;
SMR Status Monitoring:
CSU and WinCSU monitor status of the SMR:
• Output current of SMR;
• Temperature of heatsink of SMR;
• SMR alarms;
Current:
Monitored on CSU and WinCSU with 0.1A
resolution; Analogue measurement accuracy ± 1%
at full load;
Voltage:
System voltage normally displayed on CSU
alphanumeric display. Accuracy ± 0.5%
SMR Address:
DIP switches in the magazine set the SMR
address.
SMR Alarm Monitoring:
The table shows alarm conditions that are
monitored by the SMR and are displayed on both
CSU and WinCSU. The mnemonics listed here
appear on WinCSU, but full alarm description
appears on CSU;
Vh Output voltage too high
Vl Output voltage too low
Il Unit is in current limit
Po Unit is in power limit
Th Heatsink temperature high and
thermal limit is active
Lo Low output current, less than 1A.
Can be disabled
Ma Operating parameters out of range
(or EEPROM fault)
No
Response
SMR communication fault.
Generated within CSU
Sd * Unit is shut down by remote
command - user shutdown
Mr * Internal voltage reference faulty
Vs * High voltage shut down (output),
latched alarm. User setting or fault
Unit Off * Unit is shut down due to AC out of
range or SMR primary circuit fault.
(normal operation or fault)
NC * SMR incorrectly inserted into the
magazine
Tl *
Low temperature (below -40°C)
Oh * Overheat
Ts * Temperature sensor fault
Dc * DC-DC converter feedback fault,
latched alarm
NF * Fan not connected
Ff ** Fan failure
Notes: * indicates unit shut-down
** unit will shut down when H/S temperature
exceeds 20
°
C and fan speed is over 75%
of its maximum speed.
