The recommended receiver is a MAX 491 transceiver in receive mode. 2. Controller provides a series of pulses (or differential pulse pairs) on the CLOCK input lines. 3. On the first HIGH-to-LOW CLOCK transition, the encoder latches its data at the current position and prepares to transmit. 4. Controller reads data on the falling edge of the next 15 clock cycles. 5. The first bit is a START bit and is always HIGH. 6. Next comes 13 data bits beginning with the most significant bit (MSB) and ending with the parity bit. On 12 bit encoders, bit 13 is LOW. When parity is not ordered, parity is LOW. 7. After the last CLOCK HIGH-to-LOW transition, a minimum of 40 microseconds must pass before the beginning of the next CLOCK series. Ordering SSI: HOW TO SPECIFY SSI OUTPUT IN THE ENCODER MODEL NUMBER: Use the designation, S3 between the Code Format designation and the Connector designation. Example: H38D-12GC-S3-CW-SC-CEN Cable impedance can create a transmission delay, in effect, shifting the phase relationship between the clock pulse and the data. If this phase shift exceeds 180°, then the wrong bit position will be sampled by the receiver. As a result, the maximum allowable clock frequency is a function of the cable length. For 24 AWG, stranded, 3 pair cable (BEI part number 37048-003 or equivalent) the group delay is 1.36ns/ft. The table below shows the maximum transmission rate allowable as a function of cable length to ensure a phase shift of less than 90°.

A clock pulse train from a controller is used to clock out sensor data: one bit of position data is transmitted to the controller per one clock pulse received by the sensor. The use of a differential driver permits reliable transmission of data over long distances in environments that may be electrically noisy. The encoder utilizes a clock signal, provided by the user interface, to time the data transmission. Receiving electronics must include an appropriate receiver as well as line terminating resistors.

Pin 18 is normally HI (or N/C) and is pulled up internally to +V. To reverse the count direction, Pin 18 must be pulled LO (COMMON). Latch control: Encoder outputs are active and provide continuous parallel position information when Pin 17 is HI (or N/C). Pin 17 is pulled up internally to +V. When Pin 17 is LO (COMMON) the encoder outputs are latched at the logic state that is present when the latch is applied and will stay latched until Pin 17 is no longer grounded. 1. Environment: Hazardous Locations — UL Complies with UL and cUL requirements; CEN Shall comply with UL requirements plus CENELAC/ATEX plus IECEx standards 2. WARNING: Open all circuits prior to connecting this product to power and controller. 3. The installation must comply with NEC Class 2 circuits or with the regulations of the country of use. 4. AWG 14 - 22 stranded wire stripped to .25” [6.3mm} is recommended. 5. Use agency approved 105° C minimum rated cable/conductors housed within an approved rigid conduit. 6. Conduit runs must have a sealing fitting certified to 60079-0 Ex d IIB immediately at the entrance to the device. 7. Tightly close terminal block access cover prior to applying power. 8. For maximum bearing life, a flexible coupling is recommended between encoder shaft and driving shaft. 9. Thread sealant compound should be used for 1/2-14 fitting or cable gland to prevent ingress of contamination. 1. Keep terminal block access tightly secured during use. 2. DO NOT loosen two 5/16” set screws at opposite face. 1. There are no user serviceable parts inside. Encoder must be returned to factory for service. 2. WARNING: Open all circuits to this product prior to opening access cover to disconnect wires. See Doc. 01059-000 supplied with encoders for Important Installation and Usage notes summarized here.
