power supply. In either situation, specify an
electromagnetic switch, relay logic controller. If
a microprocessor is allowed, the mechanical design
for the elevator machine room must include the HVAC
recommended by the control system manufacturer.
**************************************************************************
[Provide solid-state microprocessor controller to enable programmable
control of call allocation, logic functions, door control, speed sensing
and car position. Provide a method of reprogramming adjustable parameters
of computerized controls. Store all programming in non-volatile memory.
The microprocessor control system is acceptable only if hardware and
software required to maintain and utilize microprocessor is provided and
training is provided to Government Personnel by the equipment manufacturer
and supplier.]
[Provide electromagnetic switch, relay logic control.]
2.4.2.1
Repair Requirements
**************************************************************************
NOTE: When microprocessor control system is used,
mechanical design for the project shall provide the
HVAC heating and cooling required by control
manufacturer for elevator machinery space.
**************************************************************************
For the repair of microprocessor control system, provide maintenance tools,
supporting computer software, and software documentation required for
complete maintenance of elevator system including diagnostics and
adjustments. Tools may be hand-held or built into control system. Provide
tools which do not require recharging to maintain their memory or
authorization for use. Do not use software which requires periodic
reprogramming, or reauthorization. Programs shall be stored in
non-volatile memory. Tools and software may be factory programmed to
operate only with this project's identification serial number.
