Blocks (see Section 4):
Positioner mode: The "Forced" Block Output becomes the Setpoint, and the Setpoint Input signal is ignored. That
is, when Forced, triacs activate based on the Scaled Feedback as compared to the Forced Block Output. TOUT
uses the normal Positioner logic when "Forced", and therefore requires the Position Feedback Input to be active
and Scaling Parameters 4 & 5 to be setup for proper operation.
Dual Triacs mode: +199.99% activates Triac 1, -199.99% activates Triac 2.
S/M Mode, Dual Triacs mode (See Section 4): Using the
Change one output
Service Manual submenu , pressing
the INC key will activate Triac 1 (Increase) while the INC key is pressed. The DEC key similarly activates Triac 2
(Decrease).

Notes:
1. Ignored in Dual Triac mode.
2. Ignored in Positioner mode.
3. The “G” option board has two pairs of Triacs.
4. The difference between Parameters 4 & 5 must be greater or equal to 10%.
5. Reverse Input scaling is valid, i.e. 0% POSITION = 100% Feedback, 100% POSITION = 0% Feedback.
6. Stroke time is from 0% to 100% POSITION (i.e. Scaled Feedback, NOT 0-100% Feedback Input).
7. The quantity of Outputs available is dependent on the type of option board installed. An
error message is displayed when writing Blockware to the PCC-IV if sufficient Outputs are
not available.
8. Internally limited to 0-100% range.
