External control
13.11.1
Zeroadjust
Using the floating optocoupler input on the Hydraulic Control connector (see sec.15), the GMV2-K can be snubbed
externally, e.g. be triggered by a PLC.
To control a ON level of 4 V to 30 V DC is required at least 3 mA. The OFF signal must be less than 1.5V.
13.11.2
Storing / Printing / Erasing
The save / print / delete function can be triggered externally via the 7-pole hydraulic control plug (see chapter 15 Pin
assignments). The exact function depends on the operating mode and the memory setting.

Measured-value printout to the Digimatic DP-1 HS
13.12.1
Introduction
Torque measured-values can be printed out and statistically evaluated with the "Digimatic Mini-Processor DP-1 HS"
printer. The statistics functions contain:
off-limit condition, number of measurements, max. & min. values, range, mean value, standard deviation, number of
defects, percentage defects, producible index, D board, histogram, random samples.
Parameter sets or angles of rotation cannot be printed out however.
13.12.2
Connection and preparation
The 10-pin, rectangular connector on the cable is inserted in the INPUT socket on the Digimatic printer. The 9-pin SUB-D
connector on the cable is connected with the RS-232 C socket on the GMV2-K.
DP-1 HS must be selected on the GMV2-K under "Menu / Parameter /Setting / Initial setting / Printer". The baud rate need
not be set.
The CL key must be pressed on the printer before the measured values are printed out, when no limits have been previously
transmitted. This is very important when the parameter sets are selected externally. Limits are required for many of the
statistics functions. The transmission is described in the following section.
