5. Process Monitoring
Once the
mini
CHEM
-Redox
has been installed, connected and calibrated, it can
be used for continuous monitoring. To monitor the process, WITHOUT any
control or alarm functions switch the function switch to
STANDBY
.
6. Automatic Dosing
For Automatic Alarming or Control, switch the function switch to
AUTO
to
enable the Alarm LED and the (optional) relay output. These will be switched ON
while the Redox exceeds the limit value, and will switch OFF once the Redox is
back within the limit.
7. Manual Dosing
From time to time, a dose of chemical may be required even when the Redox is
within the limit value. To do this, simply switch the function switch to
MANUAL,
if the (optional) relay output is fitted.
NOTE:
The output will be ON continuously while the function switch is set to
MANUAL
. It will not be switched OFF again until the switch is set back
to one of the other modes.
8. Fuse Replacement
If the current drain from any device connected to the output relay exceeds 1Amp,
the output protection fuse will blow.
To replace the fuse…
1.
SWITCH THE
miniCHEM-Redox
OFF.
2.
Pull out the black fuse carrier.
3.
Replace the blown fuse
4.
Push the fuse carrier with the new fuse back into place.
ALWAYS REPLACE THE FUSE WITH A 1 AMP, 240V FUSE.
USING A FUSE WITH HIGHER CURRENT RATING MAY
DAMAGE
YOUR
CONTROLLER,
VOIDING
THE
WARRANTY.
Before switching the
miniCHEM-Redox
back to
AUTO
mode, ensure that the
cause of the blown fuse has been eliminated.
If the current drain of the device connected to the relay output is greater than 1
Amp, an external contactor should be used. Please consult an electrical contractor
or TPS for details.
