send the indication. FREQ can be mapped into programmable logic. FREQ
stays picked-up until it is cleared by resetting the targets.
5.2.12 Offtap, Raise and Lower Inputs
The number of the input used to connect to the Off-Tap Switch in the
mechanism. Settings 54 through 56 define OFFTAP, RAISE, and LOWER inputs
for driving the TPM. These inputs must be set as LEVEL for proper TPM
operation. OFFTAP input signals the TPM to change its position (execute a raise
or lower operation). OFFTAP input must always be defined for proper TPM
operation. RAISE and LOWER inputs specify the direction TPM will move upon
successful operation of OFFTAP input. Only one of them (RAISE or LOWER)
must be preset before the OFFTAP input is activated in order to move the TPM
up or down into proper direction.
As stated above, It is possible to configure the TPM to operate by using only two
digital inputs. In that case specify one input for OFFTAP and another input for
either RAISE or LOWER. For example, if you specify only the RAISE input, at the
time of the OFFTAP input activating TPM will check the state of the RAISE input.
If RAISE is activated TPM will execute a raise operation and if RAISE is inactive
TPM will execute a lower operation instead. The same thing can be done with
specifying the LOWER contact. In that case the RAISE will be opposite of
LOWER.
5.2.13 Upper Limit Input
Number of the input connected to the Upper Limit Switch in the mechanism. This
resets the count in the TTC-1000 to the programmed upper limit, should the limit
switch close.
5.2.14 Lower Limit Input
Number of the input connected to the Lower Limit Switch in the mechanism. This
resets the count in the TTC-1000 to the programmed lower limit, should the limit
switch close.
5.2.15 Reset Input
Number of the input connected to the neutral switch in the mechanism. This
input will reset the count of the TTC-1000 to neutral whenever the mechanism
actually passes through neutral, should the count be in error.
5.2.16 Input Contacts
This setting is to configure the inputs for either normally open or normally closed
operation. All the inputs have this setting.
