PID Timer
This function sets a timer to monitor the amount of time the PID
controller remains at 0% or 100%. This function only appears if the PID
controller is enabled. If the timer is set to 0000, the feature is effectively
disabled. If the timer value is set to any number other zero, a FAIL
condition will occur if the PID controller remains at 0% or 100% for the
timer value. If one of the relays are set to FAIL mode, this failure
condition can be signaled by a changing relay contact.
Press ENTER to initiate user entry mode, and the entire value will flash.
Use the UP arrow key to modify desired value; range of value is 0-9999
seconds. Press ENTER to store the new value.
Sim Out
The Sim Out function allows the user to simulate the H
2
O
2
level of the
instrument in the user selected display range. The user enters a ppm
value directly onto the screen, and the output responds as if it were
actually receiving the signal from the sensor. This allows the user to
check the function of attached monitoring equipment during set-up or
troubleshooting. Escaping this screen returns the unit to normal
operation. Press ENTER to initiate the user entry mode, and the right-
most digit of the value will flash. Use arrow keys to modify desired value.
The starting display value will be the last read value of the input. The
output will be under control of the SIM screen until the ESC key is
pressed.
Note:
If the HOLD function is engaged before the Sim Output function is
engaged, the simulated output will remain the same even when the ESC
key is pressed. Disengage the HOLD function to return to normal output.
Fail Out #1
This function enables the user to define a specified value that the main
current output will go to under fault conditions. When the Relay Option
Board is installed, the display will read
Fail Out #1
. When enabled to
ON
, the output may be forced to the current value set in
Fail Val
(next
item.) With the Fail Out setting of ON, and a Fail Val setting of 6.5 mA,
any alarm condition will cause the current loop output to drop outside the
normal operating range to exactly 6.5 mA, indicating a system failure that
requires attention.
Press ENTER to initiate user entry mode, and the entire value will flash.
Use the UP arrow key to modify desired
value; selections are
ON
,
OFF
.
Press ENTER to store the new value.
Fail Val #1
Sets the output failure value for Iout#1.
When
Fail Out
above is set to
ON, t
his function sets value of the current loop under a FAIL condition.
When the Relay Option Board is installed, the display will read
Fail Out
#1
. The output may be forced to any current value between 4-20 mA.
Press ENTER to initiate user entry mode, and the entire value will flash.
Use the UP arrow key to modify desired value; selections are between
4mA
, and
20mA
. Press ENTER to store the new value.
Fail Out #2
This function sets the fail-mode of current loop output #2 under a FAIL
condition. The settings and operation are identical to Fail Out for output
#1.
