PID 4/20mA and PID/PWM control mode menus at instrument
All non digital sensor systems can be configured for PID/PWM or PID 4/20mA
control mode.
See PID/PWM and PID 4/20mA Control Mode - page 155 before configuring
sensor systems.

30 Second Aux, E-Aux and Sensor System Hold Off
Exiting aux and sensor menus after making certain configuration changes places the
system in a 30 second hold. During the 30 second sensor hold, control and alarm
systems are not active. System(s) becomes active, if, after 30 seconds, the values
are reported in control or alarm range. This 30 second hold off allows sensors and
aux devices time to stabilize before control and/or alarm systems become active.
Example - conductivity sensor menu is entered when dose up system is active and
control relay is energized. Dose up wait time is changed from 15 seconds to 45
seconds. When
to Run Screen is pressed, the conductivity system dose up
wait time is saved. Dose up relay de-energizes regardless of sensor value. Dose up
control relay re-energizes if, after 30 seconds, the value is still in control low range.
Dose up relay will energize for the new configured dose up time.
Configuring the 5200A
Configuring the 5200A
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 second
sensor system hold at the Run Screen regardless if relays are energized.
Aux and E-Aux Hold Off (non temperature aux systems)
Aux and E-Aux Hold Off (user configured) is the length of time the control or
alarm condition must exist before the Aux or E-Aux relay energizes. Temperature
(including E-Aux temperature), pH, ORP, Conductivity and DO sensor systems do
not have control hold off. These systems’ controls operate as described at set point
normal control values - page 150. Temperature (including E-Aux temperature),
pH, ORP, Conductivity and DO sensor systems alarm relays operate as described
at set point normal alarm values - page 152.
Note:
-
To avoid control or alarm for spurious events , configure the Alarm Hold Off
> than 0.

Configure digital control/alarm (open/closed), relay, alarms, and hold off in the
Aux 1 - Aux 2 and E-Aux 1 - E-Aux 8 Sensor Setup Menu.
Configure relays using
AquaManager - see page 146.
E-Aux digital systems use an IOEM digital input
as the system input. 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 a
digital system. Enabled relay will energize based on the condition configured in
the control/alarm on menu.
When enabled, Aux digital relay energizes when configured control/alarm on con-
dition 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
