Setting Up Analog Outputs
Sensing Point Outputs menu level 2.2.1
Channel
1=Chan 1 2=Chan 2
After selecting a channel, the menu automatically provides new
selections to assign sensing points.
Sensing Points 1=Add All Heads 2=Add Head 3=Del All Heads
4=Del Head 5=View Assigned 6=Save
An "X" will mark on the display to show which sensing points are assigned
to the selected channel. To keep changes, user must save assignments.
Output Parameters menu level 2.2.2
Channel
1=Chan 1 2=Chan 2
After selecting a channel, the menu automatically provides new
selections to set output parameters.
Output Signal* 1=0-5V 2=0-10V 3=4-20mA
Mode 1=Flow 2=Temp
Full Scale enter a value
Port Zero enter a value
*Set Jumpers to match. See Chapter 2.
Setting Up Relays
Relays 1 and 2 can be set as switch points or test/status parameters. If relays 1 or 2 are used for switch
points, their mode must correspond to their respective analog output channels. (e.g. If relay 1 is set to
be a flow switch point, then analog output channel 1 must be in the flow mode.) If relays 1 or 2 are set
to flow or temperature modes, the user MUST set switch point and hysteresis parameters. If this is not
done, a chattering noise will be heard. Relay 3 and 4 can only be set as test/status parameters.
Relay Mode menu level 2.2.3.1
Relay
1=Rly #1 2=Rly #2 3=Rly #3 4=Rly #4
After selecting a relay, the menu automatically provides new
parameters to set the mode.
1=View Mode 2=Flow 3=Temperature
4=System Status 5=Zero Test 6= Span Test.
Switch Points menu level 2.2.3.2
Relay
1=Rly #1 2=Rly #2 3=Rly #3 4=Rly #4
After selecting a relay, the menu automatically provides new
parameters to set the switch point.
1=View Sw. Pt. 2=Above 3=Below
4=Inside 5=Outside
Hysteresis menu level 2.2.3.3
Relay
1=Rly #1 2=Rly #2 3=Rly #3 4=Rly #4
