Steps to activate harness limit switches for normal operation and check the signal lamp.
Procedure for adjusting limit switches when the signal lamp remains off.
This document outlines the maintenance procedure for the harness limit switches on a "Spring Ride" manufactured by Moser Rides Srl. Moser Rides Srl is an Italian company located in Ostiglia (Mn), Italy, specializing in the manufacturing and sale of quality amusement rides. Their contact information includes a telephone number (++39 386 800001), a fax number (++39 386 802099), and an email address (moser@moserrides.com).
The primary function of the harness limit switches is to ensure the safety of riders by confirming that all harnesses are properly closed and secured before the ride can operate. These switches are critical components of the ride's safety interlock system. When a harness is closed, the limit switch associated with that harness is activated, sending a signal to the operator console. The system is designed such that all harness limit switches must be activated, indicating that all safety bars are closed, before the ride can proceed. This is visually confirmed by a "SAFETY BARS CLOSED" signal lamp on the operator console. The document specifically refers to a "third click" when closing the handle, which likely indicates a specific mechanical position or engagement point of the harness that triggers the limit switch.
While the document does not provide explicit technical specifications such as voltage, current ratings, or material composition of the limit switches, it implies a mechanical activation mechanism. The image on page 2 shows a lever-type limit switch, which is a common industrial component. This type of switch typically consists of a mechanical actuator (the lever) that, when depressed or moved by the closing harness, activates an internal electrical contact. The "third click" suggests a precise mechanical adjustment or a multi-stage engagement process for the harness, with the limit switch being activated at a specific point in this process. The system relies on an electrical signal to illuminate a "SAFETY BARS CLOSED" lamp on the operator console, indicating a low-voltage control circuit. The image on page 1, labeled "Fig. 1: Safety bars closed signal lamp," displays a control panel with multiple indicator lights and buttons, including a prominent "472" display, which might be a ride counter or a diagnostic code display. The green indicator light, presumably the "SAFETY BARS CLOSED" lamp, is a crucial visual cue for the operator.
The "Spring Ride" is an amusement ride, and its usage involves securing riders with harnesses. The key usage feature described in the document relates to the safety interlock system for these harnesses. For the ride to be operational, all harness limit switches must be activated, which is achieved by closing the harnesses until the "third click." This ensures that each rider is properly secured. The operator monitors the "SAFETY BARS CLOSED" signal lamp on the console to confirm that all harnesses are correctly engaged. This feature is fundamental to the safe operation of the ride, preventing it from starting if any harness is not properly closed. The design emphasizes a clear, visual confirmation for the operator, enhancing operational safety.
The document provides a detailed "PROCEDURE FOR MAINTENANCE OF THE HARNESS LIMIT SWITCHES," focusing on adjustment. The maintenance procedure is designed to ensure that all harness limit switches are correctly activated at the "third click" of the harness handle and that the "SAFETY BARS CLOSED" signal lamp illuminates on the operator console.
The maintenance steps are as follows:
If the signal lamp does not illuminate, indicating a misalignment or malfunction of the limit switch, a further adjustment procedure is outlined:
This maintenance procedure is crucial for maintaining the safety integrity of the ride. It highlights the importance of precise mechanical adjustment to ensure proper electrical signaling. The visual feedback from the operator console's signal lamp is an integral part of the adjustment process, allowing technicians to confirm correct functionality immediately. The procedure is straightforward, emphasizing practical steps for field maintenance. The image on page 2 clearly shows the limit switch with its lever and the fixing screws, providing a visual guide for the maintenance technician. The yellow arrow in the image points directly to the limit switch, indicating the component to be adjusted.
