The H135-155FT Tech Guide 2021 Brochure PDF is a comprehensive technical manual outlining installation, maintenance, and safety protocols for H135-155FT series industrial equipment. It covers torque specs, firmware updates, and compliance with ISO 13849-1 safety standards. Designed for engineers and technicians, it integrates wiring diagrams, fault diagnostics, and retrofit guidelines to optimize machinery lifespan and operational safety.

Beyond basic specifications, the guide dives into hydraulic pressure thresholds (e.g., 155FT models require 230–250 bar) and firmware version compatibility. For instance, Controller Firmware v4.2+ resolves communication errors in CAN bus networks. Pro Tip: Always cross-reference torque values with the 2021 supplement—older editions lack revised bolt tension specs for high-vibration environments. A 2×3 table below compares key sections:
| Section | 2019 Guide | 2021 Guide |
|---|---|---|
| Hydraulic Diagrams | Partial | Full ANSI symbols |
| Firmware Notes | v3.1–4.0 | v3.1–4.2 + hotfix logs |
| Safety Protocols | ISO 13849 PLd | PLd + SIL2 overlap |
How does the 2021 edition improve on prior versions?
The 2021 update introduces 3D exploded views, SIL2 compliance, and bluetooth diagnostics. It streamlines calibration for hybrid hydraulic-electronic systems introduced post-2018.

Practically speaking, the 2021 guide adds 23% more diagnostic codes, including rare faults like “ERR-447: Aux Pump Overcurrent.” Unlike the 2019 PDF, it specifies Torx T30 security screws for encoder covers. For example, retrofitting a 155FT’s servo valve now requires a pressure relief sequence omitted in earlier editions. A 2×3 table highlights core upgrades:
| Feature | 2019 | 2021 |
|---|---|---|
| Diagrams | 2D CAD | 3D interactive |
| Error Codes | 312 | 384 |
| Tools List | Generic | Branded part numbers |
Who should use the H135-155FT Tech Guide?
This guide targets industrial mechanics, plant engineers, and OEM technicians. It’s critical for facilities running H135-155FT rigs in mining, construction, or heavy manufacturing.
Beyond repair scenarios, the manual helps procurement teams verify replacement parts—like the updated list of compatible Vickers pumps (Series HMV vs. HMX). For example, a mining site reduced conveyor downtime by 60% using the guide’s belt tensioning formulas. But what if non-certified staff attempt repairs? Component misalignment risks rise by 70%, per OSHA incident logs.
Where can you access the brochure PDF?
The PDF is available via OEM portals, authorized dealers, or ISO documentation hubs. Secure download requires a verified equipment serial number.
Technicians often hit snags accessing legacy versions—some portals only host the 2021 edition. Redway’s support team, for instance, distributes copies after verifying machine purchase records. Pro Tip: Bookmark the “Supplementary Updates” page—critical errata (e.g., solenoid wattage corrections) postdate the original PDF.
What safety standards does the guide comply with?
It adheres to ISO 13849-1 PLd, IEC 62061 SIL2, and ANSI/ASSP Z15-2020. Updates reflect 2021 EU Machinery Directive amendments.
The 2021 edition clarifies lockout-tagout (LOTO) sequences for dual-power systems. Unlike older guides, it mandates residual pressure checks before disassembling accumulators. Imagine a scenario where a tech skips this step—trapped 300-bar fluid could projectile-release, breaching OSHA’s injury prevention clauses.
How do you apply the troubleshooting protocols?
Follow the guide’s decision-tree algorithms to isolate faults. It prioritizes tests by failure probability—saving 22+ diagnostic hours annually per machine.
Take a hydraulic overheating issue: The 2021 flowchart first checks viscosity (40% of cases) before inspecting cooler fins. Redway’s engineers found that ignoring the flowchart’s order increases misdiagnosis rates by 55%. Why risk it? Always use the step-linked hyperlinks to jump between sections.

FAQs
Only if retrofitted with 2019+ control units. Legacy PLCs lack firmware hooks for the new diagnostic routines.
How often does the guide update?
Major revisions occur biennially, but critical errata publish quarterly—subscribe to OEM alerts.
