subsequently.

Note 2: Depending on the Model, SP1 and SP2 may be fitted with any of three output

types, RLY, SSd or Analogue (Specification on page 11/12) where appropriate,
these must be allocated during initial configuration. SP3 is always fitted with RLY.

Re-transmission

* These models above offer the option of using the analogue output for Re-transmission.

Select

value in

LEVL 1

to equal the full range setting in

LEVL A

and if

using SP1 output, set

int.t

and

dErt.t

in

LEVL 1

to off.

Example: Set-Up using a Model 95B11P to Re-transmit the 4-20 mA input, scaled 0 to 100
units. SP1 relay is used as the control output and SP2 analogue output is used for re-
transmission.

Note: Read in conjunction with Linear Input Set-up Procedure on page 6.
