7.7 Module replacement
Vortex is a modular system, and modules can be replaced as necessary. The electronic boards
contained within the modules are not serviceable. If replacement modules are used, ensure that any
configuration switches are set correctly before they are inserted into the system (see chapter 4). The
error E001 may occur if the module address switches are incorrectly set.
See Appendix C for the list of available spare parts.
Modules can be changed without creating an error state if the Hot Swap facility of the Node Controller
Module is used.
1. To use Hot Swap, connect node controller terminal 9 to terminal 12 while in run mode (not held
on a channel). See Figure 17 in Appendix B.
During Hot Swap, the sounder sounds repeatedly and the Reading display shows the word
"Stop". The system stops monitoring, but relays remain unchanged.
2. Change the required modules. For instructions on mounting and dismounting the modules, see
section 7.8.
3. Remove the “hot swap” connection. The previous state of the Vortex system is restored and the
sounder stops.
Changing certain modules can give rise to the need to recalibrate as defined below;
Replacement of:-
Calibration Required
Node Controller Module
All channels
Quad Channel Input Module
Channels connected to replaced card
7.8 Mounting and dismounting DIN Rail modules
Modules plug into the sockets on the DIN Rail, and are held on by the plastic clips. See Figure 14.
1. To mount a module, position the top and bottom black clips in their positions closest to the plug
at the back of the module. Push the module so that the plug engages with the socket on the DIN
Rail, then push firmly until the clips engage with the DIN Rail.
2. To dismount a module, lift the top clip and lower the bottom clip using a screwdriver, as shown
in Figure 14. Pull the module off the DIN Rail.
