Page 14: Installation
Installation NOTE: • Contact Franklin Electric Technical Support for application assistance if the synchro transmitter and the 1250B monitor are separated by a wire run of more than 1200 feet. • When the installation is complete, make sure this guide is left with the site owner or operator. - Page 15 • The 1250B and the synchro transmitter must be wired to the same AC source. Do not remove the jumpers from terminals E and F. • A provided jumper or keyswitch may be installed between terminals 3 and 4 to prevent the program from being changed.

Page 16: Programming
Programming The 1250B has three methods of programming: 1. Numeric Menu 2. Alphanumeric Menu 3. Serial Port Programming Commands • Depending upon the serial port option ordered, the serial programming commands will be either RS-232 ASCII commands or RS-485 packet commands. -
Page 17: Numeric & Alphanumeric Menu Items
Numeric & Alphanumeric Menu Items To access the numeric or alphanumeric programming menu, press the MENU key for several seconds until the display goes blank, then press the SELECT / ENTER key. The display should read “OP 0”. The default menu is the numeric menu. To choose the alphanumeric menu, press the DOWN key to select OP 99. - Page 18 Alphanumeric Default Numeric Protocol Value Programmable Range Function OP 27 S Pt Any valid tap number Segmented Mode: Sets present tap position OP 28 L Pt Any valid tap number Segmented Mode: Loads present tap position into memory OP 29 dSPrL On or OFF Enables display of “r”...

Page 21: Synchro Noise Filtering
5.3.2 Synchro Noise Filtering There are some applications where the 1250B may be installed in environments where harmonic noise on the power line may cause an unstable reading of the synchro position. Assuming that a stable, steady position reading is always better than a fluctuating reading, INCON®... -
Page 22: Programming
5.3.2.1.1 Programming OP 12 (tnS F) sets the Rotation Rate Threshold for the first filter. If the synchro rotates slower than this number of degrees per second, the measured positions will be accepted as valid synchro positions, and immediately displayed. Synchro rotations faster than this rate will be ignored and assumed to be noise-induced aberrations. -
Page 23: Operating Modes
5.3.4 Operating Modes The 1250B has eight operating modes. Each mode causes the 1250B to function differently. Certain modes will have advantages in certain applications. Determine which of the following operating modes is best suited to your application: Mode # Mode Name Linear Scaled Mode Non-Linear Scaled Mode... -
Page 24: Mode 2 - Non-Linear Scaled Mode
5.3.4.2 Mode 2 – Non-Linear Scaled Mode The 1250B is capable of non-linear conversion / correction. Whenever there are two or more data point pairs in the conversion table, the 1250B will automatically switch to non-linear scaled mode. Conversion table data point pairs may be added manually or “learned”... -
Page 25: Modes 16 & 17 - Base 1 Uni-Polar Segmented
5.3.4.3 Modes 16 & 17 – Base 1 Uni-Polar Segmented These modes are used for LTC monitoring when the lowest tap number is “1”. Multiple neutral taps may be present and can be positioned anywhere between the lowest and highest taps, provided they are grouped together in a single section. To select this operating mode, use the OP 2, Func, MODE command to set the value to “16”... -

5.3.4.4 Modes 18 & 19 – Base 0 Uni-Polar Segmented These modes are used for LTC monitoring when the lowest tap number is “0”. Multiple neutral taps may be present and can be positioned anywhere between the lowest and highest taps, provided they are grouped together in a single section. To select this operating mode, use the OP 2, Func, MODE command to set the value to “18”... -
Page 27: Modes 20 & 21 - Bi-Polar Segmented
5.3.4.5 Modes 20 & 21 – Bi-Polar Segmented These modes are used for LTC monitoring when there is an equal number of raised and lowered taps. Multiple neutral taps may be present and can be positioned anywhere between the lowest and highest taps, provided they are grouped together in a single section. -
Page 28: Programming Notes
5.3.5 Programming Notes If the Degrees Per Tap value is not known, the 1250B can be used to determine this value. Follow these steps to determine the Degrees Per Tap value: 1.

Page 29: Options
1250B itself. Check the isolation of all field wiring with respect to earth ground. All wiring should be completely isolated from ground (see § 6.2). Contact Franklin Electric Technical Support for assistance if the problem persists. -
Page 30: Input Isolation Option "-I
Input Isolation Option “-I” The 1250B may be ordered with isolated input terminals. In cases where there is a compromise of the system isolation to earth ground, this option will prevent AC voltage from becoming impressed upon the analog output signal (see note at the end of § 6.1). This option consists of two small signal isolation transformers installed in the signal input circuitry. -
Page 31: Serial Rs-232
Serial RS-232 The Serial RS-232 (DCE) option on the Model 1250B can be used to program the instrument or to retrieve position data from the instrument. A Null Modem Adaptor is not needed with the provided serial cable. There are seven operating modes for the serial RS-232 port: 1. -

Page 39: Field Calibration And Test
Field Calibration and Test Calibration The 1250B should not require field calibration. However, there are provisions in the menu to facilitate Analog Output Calibration. The analog output may be adjusted in the field. A calibrated multi-meter should be used to measure the output signal during calibration. -
Page 40: Self-Diagnostic Tests
Self-Diagnostic Tests The 1250B regularly performs several self-check diagnostic tests and generates error codes in the form “FA n” and “ERR n” if it detects an internal fault. The “n” number indicates the type of failure detected. See § 8 for a full list of error codes and their descriptions. -
