Emerson Process Management CI-9110, 9110-00A Input Filter, 2 - Switch SW1 1-5, Pulse Increments

The relationship between an ON and OFF pulse time periods are shown by the following two equations:

1)T on Minimum (sec.) = (.01 SR) + K

2)T off Minimum (sec.) = K

Where:
T on Minimum =		Raise, Lower or Guard pulse
T off Minimum =		Time between pulses.
S	=	Incremental step value (Table 3-2)
R	=	Rate of output change (Table 3-3)

K= .04 sec. with R/L filter active or 0.01 sec. with R/L filter turned off. See Section 3.6 - "Output Rate of Change."

3.4 INPUT FILTER

A raise or lower input signal can contain noise pulses of an amplitude sufficient to affect the output. In these situations, switch SW1-8 can be set to activate an input filter. The switch positions are given below. For Analog models, this switch must always be set to OPEN.
