*Torque parameters: Any time the door torque parameters are changed, the Learn process must
be repeated.
** Obstruction Status: SmarTraq monitors if the door close input is active, if the door has
stopped moving, if applied torque (C3) has exceeded door closing limits. If all three conditions
are met, SmarTraq activates a “door obstruction status” output through Limit 1 or Limit 2 as
described in the preceding table (LP/LC). The obstruction status output will not clear until the
door open input is activated (removal of the door close input will not clear obstruction status).
Please refer to “Limit #1 and Limit #2” on page 9 for additional information.
Pr and Cb parameters should always be set to “00” unless it is absolutely necessary to set
them otherwise. Please refer to “Opening and Closing” on page 34 for Cb. Please refer to
“Reopening and Reclosing” on page 35 for Pr.
*C1 Maximum current threshold to establish DOL. Set according to operator characteristics.
Heavy doors and/or a geared operator that requires high torque will require a higher setting.
Light doors requiring low torque can use a lower setting. If set too high, may cause belt slip-
page and failure to establish DOL.
*C2 Maximum allowed opening torque before DOL is detected. Find the setting appropriate to
performance needs and door conditions, then increase it by 2.
*C3 Maximum allowed closing torque during normal operation: Higher value = More torque. See
the Door Closing Time compliance tables.
*Co Hold Open Torque: Higher value = More torque. Torque when doors are full open regardless
of the state of the Open command.
*Cc Hold Close Torque with Close command active: Higher value = More torque. Set to the mini-
mum necessary to keep the door closed.
*Cr Hold Close Torque when Close command is NOT active. Set to minimum necessary to keep
the door closed.
*Cd Maximum allowed torque during nudging door closing. See the Door Closing Time compliance
tables.
*Cb Braking torque: Limits braking torque during slowdown. Higher Value = More braking torque.
Lower Value = Less braking torque. 00 value = no effect. Should be set to 00 unless abso-
lutely necessary to set otherwise. See Caution following this table.
**LP Limit 1:
Higher value (non-zero): Output turns on when doors are nearer to close position.
Lower value (non-zero): Output turns on when doors are farther from full close position.
Zero value: Obstruction status assigned to Limit 1 output.
**LC Limit 2:
Higher value (non-zero): Output turns on when doors are nearer to open position.
Lower value (non-zero): Output turns on when doors are farther from full open position.
Zero value: Obstruction status assigned to Limit 2 output.
do Select Operation Mode: Once a parameter is adjusted, operation mode must be selected.
Otherwise, door operator will not respond to open or close commands.
