LEDs and status bits
The table below shows the LEDs state according to power supply voltages applied and the corresponding
status bits.
LEDs
Color State
Input Process data -
Status bit
State & Power supply voltages
UL
Off
No error
Voltage not present (UL=0 V)
If no DO configured
Powered and UB not powered
UVUL =1
Voltage not present (UL=0 V)
• If DO configured & energized
• Hub 12/4 configured with PIN 2 used as
auxiliary power
Fixed green
No error
Voltage present 19.2 V ≤ UL ≤ 30 V
Fixed red
UVUL =1
Voltage 0 V < UL <19.2 V
OVUL =1
Voltage over 30 V
OLUL =1
Overload (8 A) *
UB
Off
No error
Voltage < 11 V
• If UB < 11V, HarshIO will shutdown
• If UB > 13V, HarshIO will boot up
Fixed green
No error
Voltage present 19.2 V ≤ UL ≤ 30 V
Fixed Red
UVUB =1
Voltage 0 V < UL <19.2 V
OVUB =1
Voltage over 30 V
OLUB =1
Overload (8 A) *
(*): a ratio is applied on 8A. The real threshold is 8A x1.45
UVx: Under Voltage (x = UL or UB)
OVx: Over Voltage (x = UL or UB)
OLx: Over Load (x = UL or UB)
DO: Digital Output configured on Pin2
Note!
As IO-Link operation voltage is defined above 18V, IO-Link communication will be
reinitialized if UB goes down under 17V and comes back up to 19.2V.
