Reference*
Z
Wide reference*
Z
NOTE: Select 'standard' or 'wide' reference at time of ordering, to match the requirements
of the controller being used. Wide reference mark not available on Ti0004 interfaces.
Limits Open collector output, asynchronous pulse
Digital Ti interfaces only
Active high
Repeatability < 0.1 mm
P Q
Length of limit actuator
NOTE: No limits on TD interfaces. P limit becomes E+ for options E, F, G, H.

Alarm
Line driven*
(Asynchronous pulse)
> 15 ms
E
Alarm asserted when:
– Signal amplitude < 20% or > 135%
– Readhead speed too high for reliable operation
E− output only for Ti options A, B, C, D
or 3-state alarm
Differentially transmitted signals forced open circuit for > 15 ms when alarm conditions valid.
