Basic Safety String And Associated Wiring; Cartop Safety Switches - MCi iControl User Manual

Basic Safety String and Associated Wiring

This section contains wiring instructions for basic safety string switches (in Construction Mode,
before the iLink cartop interconnect is installed). A safety string is essentially a number of nor-
mally-closed switches connected in series such that, should any one of the switches open, power
to the motor and brake will immediately drop to stop the car. Depending upon your installation,
you may not have the exact switches described here. The job prints for your installation accu-
rately show the safety string elements at your site. In any event, the elevator must not be run
until the safety string is connected. Safety string wiring includes:
• Emergency Stop switch
• Hoistway safety switches
• Cartop safety CTS Relay temporary bypass (for Construction Mode use only)
The location and number of safety switches varies from job to job. MCE job prints indicate exact
job wiring as determined during the job survey.

Cartop Safety Switches

Depending upon the job, cartop safety switches may include:
• Safety Clamp Switch
• Emergency Exit Contact
• Emergency Stop Switch
• CTS Relay (iLink)
The wiring instructions for these switches are on the job prints.
1. Refer to the job prints.
2. Wire the cartop safety switches as shown.
Note
The Cartop Safety Relay is located in the cartop interconnect box. If the cartop box is not yet
installed, it will need to be temporarily bypassed to get the car operating in construction mode.
For now, using the switches and terminals available to you, wire as much of the string as you are
able.
