ControlWave Instruction Manual (CI-ControlWave)
Revised Nov-2010 Service & Troubleshooting 5-7
1. If the ControlWave is running, place any critical control processes
under manual control.
2. Shut down the unit by turning off the power.
3. Unplug the cables and PSSM modular connectors for power (TB2)
and watchdog (TB1).
4. Remove the bezel assembly. See Section 5.2.2 .
5. Remove the CPU module. See Section 5.2.3 . You must remove the
CPU module in order to remove the PSSM.
6. Loosen the two captured panel fasteners that secure the PSSM
module to the chassis and carefully slide it out the front of the
chassis.
7. To replace a PSSM module, power must be off and the CPU
module must be removed. Carefully align the PSSM module with
the guides for slot 1 and insert the module into the housing. When
the module correctly seats in the backplane, turn the module’s
captured panel fasteners clockwise to secure the PSSM module;
this establishes a low resistance path between the PSSM module
and chassis ground. Make sure the fasteners are tight, but don’t
over-tighten them.
8.
Replace the CPU module.
9.
Replace power and watchdog cables and then apply power and test
the unit.
5.2.5 Removing/Replacing an I/O Module (Hot Swapping)
WARNING
DO NOT ATTEMPT hot swapping in a Class I, Division 2 hazardous
location.
The ControlWave process automation controller supports removal of
any or all I/O modules from the housing while the application is
running. This is called “hot swapping.” When you initially remove or
replace any I/O module, the ControlWave halts operation for 300
milliseconds before resuming operation from where it halted. During
this momentary halt, the Port 80 display shows “CA” on its screen.
