modules, total chlorine
membrane sensor TC3 CAN and
module SiDiSens conductivity
measurement
1 Isolate the 700 P electronics module or
700 M electronics module from its power
supply. See instruction manual “700 P
electronics module” or “700 M electronics
module”.
2 Remove the housing cover of the flow
cell.
3 Take out all sensors from the mounting
hole in the cell body cover and unplug the
cable gland from DFMe electronics
module. Hold the cable while doing this as
it must not be allowed to twist.
4 Keep the sensors in a safe place (see inst-
ruction manual for sensors).
5 Disconnect CAN connection cable bet-
ween DFMe electronics module and elect-
ronic module.
6 Remove
DFMe
electronicselectronics
module from the flow cell housing. To do
this, release the fixing screw on the
underside of DFMe electronics module.
7 Unhook DFMe electronics module from
the mounting hook (design chapter 4.15-
Fig. 13) of DEPOLOX® 5 E flow cell. To do
this, raise DFMe electronics module and
carefully unhook it from the mounting
hook.
8 Open the housing of DFMe electronics
module. To do this, release the four cover
screws of DFMe electronics module.
9 Insert the optional sensor measuring
module cards in the provided slots. See
chapter 6.4 “DFMe electronics module”.
10 When installing the SiDiSens LF module
and/or the total chlorine membrane sen-
sor TC3 CAN, switch off the CAN-balan-
cing resistors on the DFMe electronics
module. Set the DIP switch (Fig. 16) to
“
OFF
“
position. Furthermore, the CAN
extension socket (chapter 4.15 - Fig. 13 -
item I) must also be retrofitted. To do this,
break out the indent on the housing
underside of DFMe electronics module
and fit the CAN extension socket. Check
that all gasket inserts are correctly moun-
ted.

11 Fit the housing cover of DFMe electronics
module and secure with the four cover
screws. Tighten the housing screws to a
maximum torque of 0.7 Nm (± 0.15 Nm).
12 Hook DFMe electronics module by the
mounting hook onto flow cell and secure
on the underside with the securing
screws.
DANGER
Risk of injury or death!
External voltages can be connected even
with the operating voltage switched off.
