Checklist for Start-Up
When installing and starting up the temperature controller module, the following instructions
regarding hardware and software must be adhered to.
All the points must be checked step by step in the order in which they occur below. If errors or
faults occur, the checklist should prove helpful in excluding user errors.
a ) Hardware
– Read the operating instructions thoroughly.
– Decide on the PLC and slot in the PLC for the IP 244.
– Select the module address within the system concept.
– Set the module address and jumpers for PESP (see Operating Instructions,
switches A76, 77).
– Select the conversion time and clock setting and insert the jumpers (see
Operating Instructions, Section 3.4).
– Connect the digital inputs and outputs to socket connector X4. Take care
with the pins of subminiature D connectors (use the preassembled
connecting cable 6ES5 721-4xxx0).
– Connect the analog signals to plug connector X3. Only use shielded cables
(use preassembled connecting cable 6ES5 721-5xxx0).
– Short circuit unused analog inputs and connect them to reference potential.
– Connect shields to shielding bars at cabinet reference potential inside the
cabinet.
– Floating sensors (isolated thermocouples) must be connected at one end
with the reference potential (common mode voltage between analog input
and reference potential maximum 1 V
– For Pt 100 operation, connect the Pt 100 element using four wires (shielded
cable).
– For Pt 100 operation, change the jumper setting as described in Part 2.
– Connect the Pt 100 element to plug connector X3 (pin assignment see
Operating Instructions, Section 2.2.1).
– Establish thermal contact between the Pt 100 and the terminals of the
thermocouples. Note the air flow within the cabinet. The Pt 100 element
should not be blown by fans.
– Connect L+ to connector X5.
– Insert the module and switch on the PLC.
