SIMPRO-100 Manual: Locating Siemens Legacy Relay Documentation

Overview

The SIMPRO-100 is a legacy Siemens numerical motor protection relay originally developed and supported by the Siemens Power Transmission & Distribution (PT&D) operating division. The platform has been formally obsoleted, which removes it from the current Siemens Industry Online Support (SIOS) catalog index and complicates retrieval of the original instruction manual (IM), parameter lists, and wiring diagrams. This reference documents the identification, retrieval, and verification procedures required to obtain the SIMPRO-100 IM for field maintenance, retrofit engineering, or forensic failure analysis.

The discussion that follows assumes the engineer is working in North America and routes through the Siemens corporate support channels operating under the current divisional structure. Where the historical portal referenced in Siemens' archived product pages is unreachable, the article provides offline archives, third-party archive services, and direct routing contacts that remain effective.

SIMPRO-100 Product Profile

SIMPRO designates a family of microprocessor-based numeric protection devices intended for low-voltage and medium-voltage motor and feeder applications. The legacy North-American product page reference for the SIMPRO family was hosted on the Siemens Energy Portal at /static/us/en/products_solutions/1847_pasimpro.html. The catalog path segment 1847 corresponds to the Siemens material-master group used by the PT&D division for North-American power-distribution products, including motor protection, low-voltage starters, and medium-voltage switchgear controllers.

The SIMPRO-100 was superseded by successive SIMPRO generations (notably SIMPRO-200 and SIMPRO-300) and ultimately by the SIMOCODE pro and SIPROTEC 4 motor/feeder protection platforms. Despite formal obsolescence, a substantial installed base persists in petrochemical, water/wastewater, mining, and pulp/paper facilities. The longevity of these installations drives ongoing field requests for the original IM, parameter sheets, and configuration documentation.

Functional scope

SIMPRO-100 performs the following protection and metering functions (per faceplate label and standard SIMPRO family documentation; verify against the IM for the exact variant):

• Three-phase current monitoring with true-RMS conversion
• Thermal-model overload protection with selectable curves
• Phase unbalance and phase-loss detection
• Ground-fault (earth-leakage) detection via core-balance or residual CT
• Trip and alarm auxiliary relays with field-selectable logic
• Front-fascia LED status indication (run, trip, alarm, ready)
• Test/Reset pushbutton interface on the front fascia
• Optional mechanical or electronic reset coil

Typical application environments

• Squirrel-cage induction motors, 50-6300 A (via external CT)
• Critical process pumps, compressors, and conveyors in continuous-duty service
• Motors in NEMA 1 / IP54 control compartments (verify variant enclosure rating)
• Systems where reverse compatibility of trip curves with downstream circuit breakers is required

Identifying SIMPRO-100 Variants and Material Numbers

Before contacting Siemens, gather the following data from the device faceplate, side label, and nameplate. Without these, the routing specialist cannot resolve the archive request; partial answers are returned as "documentation not available."

Locating the Official Instruction Manual

The historical Siemens product portal location for SIMPRO-100 was:

• Host: energy-portal.siemens.com
• Path: /static/us/en/products_solutions/1847_pasimpro.html

This page exposes the IM download only after the visitor selects More Information in the page footer; the link is not present at the top-level entry. If the link is missing, the page renders to product-overview content only. If the page itself returns a 404, the entry has been retired from the live portal and the IM must be requested through the offline archive (see Alternative Documentation Channels).

Step-by-step retrieval from the live portal

1. Open the product URL in a desktop browser. Mobile rendering sometimes hides the More Information link.
2. Disable strict cookie/tracker blocking for the energy-portal.siemens.com domain; the Siemens download tracker rejects requests that omit the session cookie.
3. Scroll to the bottom of the page; click More Information.
4. From the expanded panel, select Instruction Manual (PDF, typically 1.5-4 MB).
5. Save the PDF with the material number in the filename: SIMPRO100_1847-XXXX_IM.pdf.
6. Verify the PDF page count matches the table of contents in section 1 of the IM.

Programmatic availability check

Use an HTTP HEAD request to confirm the resource is still hosted:

curl -I https://www.energy-portal.siemens.com/static/us/en/products_solutions/1847_pasimpro.html
# Expected: HTTP/2 200 OK, content-type: text/html
# 404: Archive offline; proceed to offline channels.

A 301 or 302 response indicates an internal portal reorganization; follow the redirect target and re-test the IM link.

Alternative Documentation Channels

When the live portal returns 404 or the IM PDF is no longer reachable, use the following fallback list in priority order.

1. Siemens Industry Online Support (SIOS) archive search. Filter by product family "SIMPRO" and document type "Instruction Manual." Reference: Siemens Industry Online Support.
2. Siemens 1-800-SIEMENS support line (US/Canada). Route directly to the PT&D specialty queue; provide the material number collected above.
3. Authorized Siemens distributor with PT&D product access. Larger distributors maintain archived CD-ROM libraries from Siemens.
4. Internet Archive Wayback Machine for historical captures of the energy-portal page and any linked PDF. Reference: web.archive.org.
5. Field service historical libraries maintained by large systems integrators, EPC firms, and OEM panel builders.
6. Siemens customer service e-mail archive request for retired products; turnaround time 1-5 business days.

Navigating Siemens' Divisional Support Structure

Siemens operates multiple parallel organizational entities that make first-line contact resolution non-trivial. Field experience confirms that calling the wrong division is the dominant cause of stalled documentation requests. The four divisions most likely to interact with a SIMPRO-100 inquiry are:

• PD&C (Power Distribution & Control) - motors, drives, low-voltage controls.
• PT&D (Power Transmission & Distribution) - medium/high-voltage switchgear, transmission, substation automation; this is the division that historically owned SIMPRO.
• DI / IA (Digital Industries / Industrial Automation) - PLCs, drives (SINAMICS), I/O.
• Smart Infrastructure - building automation.

The 1-800-SIEMENS front-end maintains a group of specially trained routing specialists; always request PT&D documentation routing for SIMPRO product questions.

Specifications, Ratings, and Configuration Parameters

Detailed SIMPRO-100 electrical ratings are not reproduced verbatim in this reference because the exact variant values must be confirmed against the IM and the device nameplate. The following parameter categories appear on every faceplate and should be cross-checked against the IM section referenced. Each row is labeled with the IM section where the value is defined; the engineer must read that section for the variant-specific value before energizing.

Field Commissioning and Verification Procedures

Use the following commissioning checklist when installing, replacing, or resetting a SIMPRO-100 in the field. The procedure assumes the IM has been retrieved per the prior sections and the engineer has confirmed CT polarity and auxiliary supply against the IM.

1. Mechanical inspection. Confirm fascia, lens, lens gasket, and seal integrity. Replace if damaged; moisture ingress is the leading cause of PCBA failure in field units.
2. Verify CT ratio programming. Match CT primary and CT secondary against nameplate and IM section 4.
3. Apply control power. Energize auxiliary supply at the level stamped on the nameplate only.
4. Self-test. Initiate the built-in self-test cycle from the fascia pushbutton. Confirm all status LEDs illuminate per IM section 9 test sequence.
5. Primary injection test. Using a 3-phase injection set, apply rated current; verify the unit tracks magnitude within the IM tolerance.
6. Thermal trip verification. Apply 6x pickup current; verify trip time matches the selected class curve within the IM tolerance.
7. Unbalance trip verification. Apply 3-phase current with one phase reduced; verify unbalance threshold and time delay per IM section 6.
8. Ground-fault trip verification. Apply zero-sequence current through the appropriate CT; verify pickup per IM section 7.
9. Trip contact verification. Measure contact transition with a continuity tester; record drop-out and operate times.
10. Alarm contact verification. Repeat for any auxiliary alarm relays.
11. Restore wiring and reset. Re-seal the fascia and reset any latched trips via the fascia pushbutton before returning to service.
12. As-built configuration record. Stamp the IM page that lists all settings, date and initial; store with the device maintenance log.
