Module Power Supply

This module requires an external DC power source for operation. The nominal supply voltage is 28 VDC, with the allowable operating voltage range spanning from 27.4 VDC to 28.6 VDC. The maximum input current reaches 0.41 A under full operating load, and the overall maximum power consumption of the module is limited to 25 W to ensure stable long-term operation within the control cabinet.

Field Signal Inputs

Emergency Stop Input accepts signal voltage ranging from 18 VDC to 140 VDC for safety interlock signal acquisition.

Voltage Protection Trip Inputs support input voltages between 16 VDC and 140 VDC to monitor critical trip trigger signals.

Magnetic Speed Pickup Inputs are designed to process pulse signals within the voltage range of -15 VDC to +15 VDC for rotational speed detection.

Trip Contact Output

The relay contact output features a rated switching voltage range of 24～28 VDC. It supports a maximum switching current of 7 A, capable of driving external trip circuits and related field actuation devices.

Fault 1: PWR LED Remains Off, Module Cannot Boot Normally

Possible Causes

The supplied 28 VDC power deviates from the specified operating range of 27.4~28.6 VDC

Loose power terminals, defective cable contacts or broken power wires

Internal short circuit on the module circuit leading to abnormal power draw

Solutions

Measure the input voltage to verify compliance with specifications. Retighten power terminals and inspect cable integrity. Remove and reinstall the module securely onto the TTURH1C terminal board. If the issue persists after wiring inspection, replace the module for testing. Ensure the input current never exceeds the maximum rating of 0.41 A.

Fault 2: Flashing ENET LINK LED or Loss of Communication with Mark VIe Controller

Possible Causes

Damaged Ethernet cable, poor RJ45 contact or incorrect network wiring layout

Mismatched network parameters between the module and main controller

Incompatible or corrupted module firmware

Electromagnetic interference disrupting data transmission

Solutions

Swap out the cable with a fully tested Ethernet line and reseat RJ45 plugs. Download compatible firmware via Toolbox software and double-check IP addresses and redundancy configurations. Route network cables separately from high-power cables and implement standard shielding and grounding to mitigate interference. Restart the module after finishing parameter adjustments.

Fault 3: Loss of Magnetic Speed Pickup Input, Incorrect Speed Readings and Pulse Error Alarms

Possible Causes

Damaged magnetic pickup sensor or improperly adjusted sensor air gap

Open circuits, short circuits or inadequate shielding of signal cables

Insufficient signal amplitude to meet the receiving threshold at low rotation speeds

Loose connectors on the terminal base

Solutions

Check and calibrate the mounting clearance of the magnetic pickup transducer and test its output waveform. Verify wiring continuity and troubleshoot short-circuit issues. Rearrange cable paths to stay away from interference sources. Adjust the trigger threshold for speed signals via configuration software and firmly lock all terminal connectors.

Fault 4: Failure to Detect Emergency Stop / Trip Input Signals

Possible Causes

Field input voltage outside the valid working range of 18~140 VDC

Open circuits within the E-stop loop or loose wiring terminals

Oxidized contacts on external emergency stop relays

Solutions

Measure the field signal voltage and test the continuity of the entire emergency stop circuit. Clean or replace aging relay contacts. Secure all wiring terminals mounted on the TTURH1C base terminal board.

Fault 5: Trip Contact Output Fails to Activate the Load Circuit

Possible Causes

Load voltage exceeds the rated 24~28 VDC operating range

Load current surpasses the maximum 7 A rating and triggers internal relay protection

Degraded internal trip relay contacts or broken output wiring

Solutions

Confirm load voltage and current are within the module’s rated specifications. Install an intermediate relay for current expansion if the load draws excessive current. Inspect continuity of output wiring. Replace the module if internal relay contact failure is confirmed.

Fault 6: Occasional Random Failures and Unstable Signal Acquisition

Possible Causes

Poor physical contact between IS220PTURH1B and the terminal base

Improper system grounding and severe electromagnetic interference

Excessive ambient temperature resulting in unstable module performance

Vibration loosening wiring terminals over time

Solutions

Cut off power supply, pull out and reinsert the module completely. Optimize cabinet grounding layout and separate signal cables from power cables. Enhance cabinet ventilation to regulate ambient operating temperature. Retighten all terminals and add anti-vibration reinforcements for the control cabinet.

Fault 7: Unable to Download Configuration; Settings Lost After Power Cycle

Possible Causes

Firmware version incompatible with the Mark VIe system

Faulty internal non-volatile memory of the module

Communication interruption occurring during configuration download

Solutions

Install the officially matched firmware version. Prevent power loss during program downloading. Re-transfer all configuration parameters and conduct power cycle verification. Replace the module if configurations still cannot be stored reliably.
