WIRING

GENERAL

The Model 1056 is easy to wire. It includes removable connectors and slide-out signal input boards. The front panel is hinged at the bottom. The panel swings down for easy access to the wiring locations.

Removable connectors and signal input boards

Model 1056 uses removable signal input boards and communication boards for ease of wiring and instal- lation. Each of the signal input boards can be partially or completely removed from the enclosure for wiring. The Model 1056 has three slots for placement of up to two signal input boards and one communication board.

Signal Input boards

Slots 2 and 3 are for signal input measurement boards. Wire the sensor leads to the measurement board following the lead locations marked on the board. After wiring the sensor leads to the signal board, carefully slide the wired board fully into the enclosure slot and take up the excess sensor cable through the cable gland. Tighten the cable gland nut to secure the cable and ensure a sealed enclosure.

Digital Communication boards

A Profibus DP communication board is available as an ordering option for Model 1056 digital communication. Profibus DP is an open communications protocol which operates over a dedicated digital line to the host. HART digital communications are also available as an ordering option. HART circuitry is embedded in the main PCBA; there is no separate slide-in communications board. HART supports Bell 202 digital communications over an analog 4-20mA current output.

Alarm relays

Four alarm relays are supplied with the switching power supply (84 to 265VAC, -03 order code) and the 24VDC power supply (20-30VDC, -02 order code). All relays can be used for process measurement(s) or temperature. Any relay can be configured as a fault alarm instead of a process alarm. Each relay can be configured independently and each can be programmed as an interval timer, typically used to activate pumps or control valves. As process alarms, alarm logic (high or low activation or USP*) and deadband are user-programmable. Customer-defined failsafe operation is supported as a programmable menu function to allow all relays to be energized or not-energized as a default condition upon powering the analyzer.

The USP* alarm can be programmed to activate when the conductivity is within a user-selectable

percentage of the limit. USP alarming is available only when a contacting conductivity measurement board is installed.

PREPARING CONDUIT OPENINGS

There are six conduit openings in all configurations of Model 1056. (Note that four of the openings will be fitted with plugs upon shipment.)

Conduit openings accept 1/2-inch conduit fittings or PG13.5 cable glands. To keep the case watertight, block unused openings with NEMA 4X or IP65 conduit plugs.

NOTE: Use watertight fittings and hubs that comply with your requirements. Connect the conduit hub to the conduit before attaching the fitting to the analyzer.
