Temporary CTS Relay Bypass
If the iLink cartop interconnect box which contains the Cartop Safety (CTS) Relay is not yet
installed, you must bypass the CTS relay temporarily (for Construction Mode only). (If you are
installing the iLink cartop box now, please refer to the iLink instructions in Section 3.)
1. Refer to the job prints.
2. Connect the safety string in series between the iBox SAFH and SAFC terminals.
3. You must provide an Emergency Stop switch in series between SAFH and SAFC.
Danger
Make sure the Emergency Stop switch is wired in series between SAFH and SAFC to allow emergency
stopping while working on the cartop.
Access Locks and Contacts
Door switches include:
• Car door: GS (Gate Switch).
• Hall doors: DLMS (Door Lock Main String), DLAT (Door Lock Access Top), DCAT (Door
Contact Access Top), DLAB (Door Lock Access Bottom), DCAB (Door Contact Access Bot-
tom).
1. Refer to the job prints.
2. Connect the switches for front and rear (if present) doors as shown.
Rope Gripper Wiring
An “emergency brake” may be connected between iControl terminals RG1 and RG2 to stop
unexpected car motion. A rope gripper is used to apply braking pressure to the hoist ropes.
After it is triggered, press the iBox Fault Reset button or the Rope Gripper board reset button to
reset the rope gripper.
1. Refer to the job prints (MRW- machine room wiring sheets).
2. Connect the rope gripper to iControl RG1, RG2, RG5, and RG7 terminals as shown.
Temporary Rope Gripper Bypass
If a Rope Gripper will be installed later, you may temporarily bypass the input by installing a
jumper between RG5 and RG7.
Temporary Cartop Inspection Wiring
Four cartop switches control car motion: An
Inspection Enable switch, a Safe switch, an Up
switch, and a Down switch.
1. Refer to job print drawing -CW, Cartop
Inspection Station.
2. Connect the (Normally Closed) Cartop
Inspection Enable switch between the #3
bus and the iControl INCT terminal as
shown. (This switch is used to put the car on cartop inspection. INCT is active low.)
