Commissioning/Troubleshooting in a Powered State
Binary Inputs, 24 Vac Detect- Methods 1 or 2
Binary Inputs- Based on Analog Output Connection
General Information and Checkout Procedure
Measurement
Expected Value
Method 1
:
Voltage across binary input measured without reference to chassis
ground.
Measure AC voltage across
the binary input
Vac
≈
0.0 V (state = ON)
Vac
≈
24.0 V (state = OFF)
Method 2
:
Voltage across binary input measured with reference to chassis
ground. Any connection with chassis ground symbol can serve as a
ground reference for this method.
Measure DC voltage across
the binary input
Vac
≈
0.0 V (state = OFF)
Vac
≈
24.0 V (state = ON)

Measurement
Expected Value
The UC600 analog output
connections can be
configured as binary
inputs. This can be used
only with dry contact or
open collector-type
sensors.
Step 1
Measure AC voltage across the
binary input
Vac
≈
0.0 V
AC voltage will affect further measurement
Step 2
Measure DC voltage across the
binary input
Vdc
≤
2.0 V (state = ON)
