TRM138
The selected LU is switched to manual control mode by momentary depression the button
and is monitored by flashing light on the DI4 indicating device. The OU related to it is switched
to manual control mode by momentary depression or buttons. The command execution is
monitored by the К1 LED. ATTENTION! At manual control operation any command is executed by
the OU irrespective of the status of input signals from the LU until canceling. The issued command
is canceled by repeated momentary depression or buttons.
The LU is switched to automatic control mode by momentary depression button and is
monitored by the flashing light of the DI4 indicating device.
Note. Manual operation cannot be engaged when an OU is connected simultaneously to several LUs.
7.2. PROGRAMMING Mode
7.2.1. The PROGRAMMING mode is intended to configure the TRM138 circuit and to set
(change) programmed parameters’ values. The set (changed) values of the parameters are
recorded in the nonvolatile memory by momentary depression button and are stored there at
the instrument’s deenergization. The instrument starts operating with the changed values right
after their recording to the memory. In the PROGRAMMING mode the instrument keeps on metering
input values (without displaying them on the digital indicator) and generating signals for automatic
control of peripherals.
7.2.2. The instrument is switched from the OPERATION mode to the PROGRAMMING mode
by depressing and holding button for 3 sec (until the ProG prompt appears on the DI1
indicating device, and the PL0 prompt – on the DI2 indicating device). The level for the
parameters’ review or change is selected according to Figure 16.
Note. Presentation of any control button on the diagrams without indication of timing characteristics means
its momentary depression for 0.5 sec.
7.2.3. The instrument is switched from the PROGRAMMING mode to the OPERATION mode
by depressing button.
7.2.4. All programmed parameters of the instrument (according to their purpose) are divided
into six groups (levels) PL0…PL5 .
7.3. ADJUSTMENT Mode
The ADJUSTMENT mode is intended to restore the instrument’s metrological characteristics
after a longterm operation or repair related to input date measuring pattern.
The instrument adjustment procedure is presented in Appendix 5 .
