YSI Incorporated 105 5200 Recirculating System Monitor
Alarm System
The alarm system can be turned on or off. When on, an audible alarm will sound on the YSI 5200 and an
alarm page will be sent (if paging is enabled). The alarm will remain on until a key is pressed. See 7.1
Alarm Logic Flow Charts for details.
Hold Off
Hold Off is the number of seconds that the 5200 will wait before activating a control relay or generating
an alarm. The hold off time is selectable from 0 to 255 seconds
Relay
Relay Disabled
Relay Disabled is the default setting. It prevents Input #2 from triggering any relays (Internal or SubNet).
Relay Internal
Select Relay internal to trigger one of the four internal relays in this 5200.
Relay SubNet
See 7.2 General Alarm, Relay SubNet.
Min/Max Values
Min
Enter the parameter value that corresponds to the minimum input level (0V or 4mA). Example—when
using the YSI 5566 to measure TGP (Total dissolved Gas Pressure), enter “-400” as the Min value.
Max
Enter the parameter value that corresponds to the maximum input level (1V, 5V or 20mA). Example—
when using the YSI 5566 to measure TGP, enter “+400” as the Max value.
Scale
Range
Select the input type and range, 0–1VDC, 0–5VDC, or 4–20mA. Example—when using the YSI 5566 to
measure TGP, select 0–5VDC.
Format
Select the resolution (number of decimal places displayed) for the input parameter:
0
0.0
0.00
Example—when using the YSI 5566 to measure TGP, select “0.0” as the format.
Suffix
Enter up to 4 characters to be displayed as the suffix (units) for the input parameter. Example—when
using the YSI 5566 to measure TGP, enter “mmHg” as the suffix.
Label
Enter up to 4 characters to be displayed as the label (name) for the input parameter. Example—when
using the YSI 5566 to measure TGP, enter “TGP” as the label.
