Reconfiguration of the following does not place the system in 30 second hold off:
- DO systems - display format, membrane type, manual ppt input and
elevation.
- Temperature system - display format, chiller on time, chiller on time
units, chiller hold off time and chiller hold off time units.
Notes:
- Configuration changes place only the system that has been reconfigured
on 30 second hold.
- No “off” event log is created when energized system relays de-energize
due to 30 second sensor hold off.
- Control icons and control messages continue to display during the 30 sec-
ond sensor system hold at the Run Screen regardless if relays are energized.
Aux Hold Off
Aux Hold Off (user configured) is the length of time the control or alarm condition
must exist before the Aux relay energizes.
Notes:
- To avoid control or alarm for spurious events , configure the Alarm Hold
Off > than 0.
- If General Alarm is enabled, it is triggered after the Aux hold off time and
not the general alarm hold off time.
Aux Digital
Configure digital control/alarm (open/closed), relay, alarms, and hold off in the Aux
1 - Aux 2 Sensor Setup Menu. Use digital input type for control, or alarm, based on
either a switch open or switch closed condition. Only one relay can be configured in
an aux digital system. Enabled relay will energize based on the condition configured
in the control/alarm on menu.

Menus → Sensor Setup→Aux 1-2
When enabled, Aux digital relay energizes when configured control/alarm on condi-
tion occurs. Aux relay energizes after configured aux hold off time. When alarms
are disabled and as long as control/alarm on condition exists, the relay remains
energized including when menus are entered. Relay de-energizes when the non
control/alarm condition is processed by the 5200A regardless if alarms are enabled.
If alarms are enabled, the relay also de-energizes when one of the four front panel

softkeys is pressed. Pressing one of four softkeys
resets the alarm system. The Alarm system becomes active again if, after the aux
hold off period, the alarm condition still exists.
Aux digital events (event log) are identified by aux number, input type (digital), relay
condition (on/off), and do not identify digital condition (open, or closed). Aux digital
events are not identified as control or alarm events regardless if alarms are enabled.
Directions to Configure Aux (digital)
1. Wire Aux digital devices - page 49.
2. Configure “digital” at Menus → System → Configure Aux →Input Type
3. Enter Aux 1-2 in Sensor Setup menu
Menus → System → Sensor Setup → Aux 1-2

Notes:
- It is important to keep the 5200A at the Run Screen during normal
operation. Alarm functionality (email alarms, activation of enabled
alarm relays, alarm icons, and buzzer) is suspended when 5X00 is not
at Run Screen.
- At sensor log Aux (1:1.00 ) is reporting open condition. Aux (1: 0.00) is
reporting closed condition.
- An aux digital relay will energize when alarms are enabled if in menus
longer than the aux alarm hold off time and the control/alarm condition
is processed from an existing non control/alarm condition. The general
alarm will not trigger until the user exits to run screen, the control/alarm
condition is reset by processing a non control/alarm condition, AND then
a control/alarm condition is reproduced.
