Sensor Operation
Diagnostics
Note: The following applies to an MN-S3, MN-S3HT, MN-S4, MN-S4HT, MN-S4-FCS, MN-
S4HT-FCS, MN-S5, or MN-S5HT sensor connected to a TAC I/A Series MicroNet
controller.
In the Diagnostics Mode, the sensor times out and returns to the default screen if left idle for
forty seconds. Subnet Address, Node Address, Alarms, and Errors are view only frames.
Values displayed in the Temperature Offset and Relative Humidity Offset frames are
adjustable.
The TAC I/A Series MicroNet MN-S3, MN-S3HT, MN-S4, MN-S4HT, MN-S4-FCS,
MN-S4HT-FCS, MN-S5, or MN-S5HT Sensors provide the following types of diagnostic
data.
To access view only diagnostics:
View the Subnet Address, Node Address, Errors, and Alarms in this mode.
1. Press and hold both ends of Up/Down Key for four seconds. The Subnet Address frame
appears.
2. Press Up/Down Key to scroll through Node Address frame, Errors frame, and Alarms
frame.
To access adjustable diagnostic data:
Access Temperature Offset frame and Relative Humidity Offset frame in this mode. Skip
step 1 if you are already in the Diagnostics Mode.
1. Press and hold Up/Down Key for four seconds. The Subnet Address frame appears.
2. Press Override Key. (Press On/Off/Auto key on MN-S4-FCS or MN-S4HT-FCS.) The
Temperature Offset frame appears.
3. Use Up/Down Key to adjust value.
4. To access Relative Humidity Offset frame, press Override Key (On/Off/Auto key on
MN-S4-FCS or MN-S4HT-FCS) again and use Up/Down Key to adjust value.
5. To return to the Subnet Address frame, Node Address frame, Errors frame, and Alarms
frame, press Override Key (On/Off/Auto key on MN-S4-FCS or MN-S4HT-FCS).
Subnet Address and Node Address:
Subnet Address frames and Node Address frames
display subnet and node addresses of the connected TAC I/A Series MicroNet Controller.
The LCD alternates between Subnet Address frame, numerical value of subnet address,
Node Address frame, and numerical value of node address. The values displayed reflect the
subnet/node address assigned to domain table index 0.
